commit b9a758a8c905fc59e783ae91ad645452d877ea88 upstream.
The initial USB driver did not use some register save locations in the
private data storage. To save some memory, a union was used to overlay these
variables with USB I/O components. In an update of the gain-control code,
these register save locations are now needed for USB drivers.

If the bus loading is not high, the imx28 usb can work well at the most
of time. There is a IC errata for this problem, usually, we consider
IC errata is a problem not a new feature, and this workaround is needed
for that, so we need to add them to stable tree 3.11+.

commit 543d7784b07ffd16cc82a9cb4e1e0323fd0040f1 upstream.
There is a race in the hub driver between hub_disconnect() and
recursively_mark_NOTATTACHED(). This race can be triggered if the
driver is unbound from a device at the same time as the bus's root hub
is removed. When the race occurs, it can cause an oops:

One problem is that recursively_mark_NOTATTACHED() uses the intfdata
value and hub->hdev->maxchild while hub_disconnect() is clearing them.
Another problem is that it uses hub->ports[i] while the port device is
being released.
To fix this race, we need to hold the device_state_lock while
hub_disconnect() changes the values. (Note that usb_disconnect()
and hub_port_connect_change() already acquire this lock at similar
critical times during a USB device's life cycle.) We also need to
remove the port devices after maxchild has been set to 0, instead of
before.

commit 0e16114f2db4838251fb64f3b550996ad3585890 upstream.
The USB storage operation of Nokia Asha 502 Dual SIM smartphone running Asha
Platform 1.1.1 is unreliable in respect of data consistency (i.e. transfered
files are corrupted). A similar issue is described here:
http://discussions.nokia.com/t5/Asha-and-other-Nokia-Series-30/Nokia-301-USB-transfers-and-corrupted-files/td-p/1974170
The workaround is (MAX_SECTORS_64):
rmmod usb_storage && modprobe usb_storage quirks=0421:06aa:m

commit c1f15196ac3b541d084dc80a8fbd8a74c6a0bd44 upstream.
Genuine FTDI chips support only CS7/8. A previous fix in commit
8704211f65a2 ("USB: ftdi_sio: fixed handling of unsupported CSIZE
setting") enforced this limitation and reported it back to userspace.
However, certain types of smartcard readers depend on specific
driver behaviour that requests 0 data bits (not 5) to change into a
different operating mode if CS5 has been set.
This patch reenables this behaviour for all FTDI devices.
Tagged to be added to stable, because it affects a lot of users of
embedded systems which rely on these readers to work properly.

commit 623c8263376c0b8a4b0c220232e7313d762cd0cc upstream.
Some PL2303 devices are known to lose bytes if you change serial
settings even to the same values as before. Avoid this by comparing the
encoded settings with the previsouly used ones before configuring the
device.
The common case was fixed by commit bf5e5834bffc6 ("pl2303: Fix mode
switching regression"), but this problem was still possible to trigger,
for instance, by using the TCSETS2-interface to repeatedly request
115201 baud, which gets mapped to 115200 and thus always triggers a
settings update.

commit 2fc5a7dace3c43e62402ab4e8800a8f1834ffe2a upstream.
We have met a bug that the high bandwidth ISO-TX transfer has failed
at the last packet if it is less than 1024, the TD status shows it
is "Transaction Error".
The root cause of this problem is: the mult value at qh is not correct
for current TD's transfer length. We use TD list to queue un-transfer
TDs, and change mult for new adding TDs. If new adding TDs transfer length
less than 1024, but the queued un-transfer TDs transfer length is larger
than 1024, the transfer error will occur, and vice versa.
Usually, this problem occurs at the last packet, and the first packet for
new frame.
We fixed this problem by setting Mult at QH as the largest value (3), and
set MultO (Multiplier Override) at TD according to every transfer length.
It can cover both hardware version less than 2.3 (the real mult is MultO
if it is not 0) and 2.3+ (the real mult is min(qh.mult, td.multo)).
Since the MultO bits are only existed at TX TD, we keep the ISO-RX behavior
unchanged.

bios major version, look at the BMP version. BIOSes with BMP version 0
do not contain a detectable script, so always return 0 for them.

commit 9f97e4b128d2ea90a5f5063ea0ee3b0911f4c669 upstream.
Before a write starts we set a bit in the write-intent bitmap.
When the write completes we clear that bit if the write was successful
to all devices. However if the write wasn't fully successful we
should not clear the bit. If the faulty drive is subsequently
re-added, the fact that the bit is still set ensure that we will
re-write the data that is missing.
This logic is mediated by the STRIPE_DEGRADED flag - we only clear the
bitmap bit when this flag is not set.
Currently we correctly set the flag if a write starts when some
devices are failed or missing. But we do *not* set the flag if some
device failed during the write attempt.
This is wrong and can result in clearing the bit inappropriately.
So: set the flag when a write fails.
This bug has been present since bitmaps were introduces, so the fix is
suitable for any -stable kernel.

commit 7ad228b11ec26a820291c9f5a1168d6176580dc1 upstream.
When the pipe A force quirk is applied the code will attempt to grab
a crtc mutex during intel_modeset_setup_hw_state(). If we're already
holding all crtc mutexes this will obviously deadlock every time.
So instead of using drm_modeset_lock_all() just grab the
mode_config.mutex. This is enough to avoid the unlocked mutex warnings
from certain lower level functions.
The regression was introduced in:

commit fe43390702a1b5741fdf217063b05c7612b38303 upstream.
When the pl011 is being used for a console, pl011_console_write forces
the control register (CR) to enable the UART for transmission and then
restores this to the original value afterwards. It does this while
holding the port lock.
Unfortunately, when the uart is started or shutdown - say in response to
userland using the serial device for a terminal - then this updates the
control register without any locking.
This means we can have
pl011_console_write Save CR
pl011_startup Initialise CR, e.g. enable receive
pl011_console_write Restore old CR with receive not enabled
this result is a serial port which doesn't respond to any input.
A similar race in reverse could happen when the device is shutdown.
We can fix these problems by taking the port lock when updating CR.

commit 1cc03eb93245e63b0b7a7832165efdc52e25b4e6 upstream.
commit 5d8c71f9e5fbdd95650be00294d238e27a363b5c
md: raid5 crash during degradation
Fixed a crash in an overly simplistic way which could leave
R5_WriteError or R5_MadeGood set in the stripe cache for devices
for which it is no longer relevant.
When those devices are removed and spares added the flags are still
set and can cause incorrect behaviour.
commit 14a75d3e07c784c004b4b44b34af996b8e4ac453
md/raid5: preferentially read from replacement device if possible.
Fixed the same bug if a more effective way, so we can now revert
the original commit.

commit b50c259e25d9260b9108dc0c2964c26e5ecbe1c1 upstream.
If we discover a bad block when reading we split the request and
potentially read some of it from a different device.
The code path of this has two bugs in RAID10.
1/ we get a spin_lock with _irq, but unlock without _irq!!
2/ The calculation of 'sectors_handled' is wrong, as can be clearly
seen by comparison with raid1.c
This leads to at least 2 warnings and a probable crash is a RAID10
ever had known bad blocks.

commit e8b849158508565e0cd6bc80061124afc5879160 upstream.
commit e875ecea266a543e643b19e44cf472f1412708f9
md/raid10 record bad blocks as needed during recovery.
added code to the "cannot recover this block" path to record a bad
block rather than fail the whole recovery.
Unfortunately this new case was placed *after* r10bio was freed rather
than *before*, yet it still uses r10bio.
This is will crash with a null dereference.
So move the freeing of r10bio down where it is safe.

commit 8313b8e57f55b15e5b7f7fc5d1630bbf686a9a97 upstream.
If an array is started degraded, and then the missing device
is found it can be re-added and a minimal bitmap-based recovery
will bring it fully up-to-date.
If the array is read-only a recovery would not be allowed.
But also if the array is read-only and the missing device was
present very recently, then there could be no need for any
recovery at all, so we simply include the device in the read-only
array without any recovery.
However... if the missing device was removed a little longer ago
it could be missing some updates, but if a bitmap is present it will
be conditionally accepted pending a bitmap-based update. We don't
currently detect this case properly and will include that old
device into the read-only array with no recovery even though it really
needs a recovery.
This patch keeps track of whether a bitmap-based-recovery is really
needed or not in the new Bitmap_sync rdev flag. If that is set,
then the device will not be added to a read-only array.

commit 0882dae983707455e97479e5e904e37673517ebc upstream.
Properly zero the refcounts and crtc->ddi_pll_set so the previous HW
state doesn't affect the result of reading the current HW state.
This fixes WARNs about WRPLL refcount if we have an HDMI monitor on
HSW and then suspend/resume.

commit 3f9aec7610b39521c7c69d754de7265f6994c194 upstream.
When the core number exceeds 9, the size of the buffer storing the
alarm attribute name is insufficient and the attribute name is
truncated. This causes libsensors to skip these attributes as the
truncated name is not recognized.

commit af73623f5f10eb3832c87a169b28f7df040a875b upstream.
Somehow older areca firmware versions have issues with
scsi_get_vpd_page() and a large buffer, the firmware
seems to crash and the scsi error-handler will start endless
recovery retries.
Limiting the buf-size to 64-bytes fixes this issue with older
firmware versions (<1.49 for my controller).
Fixes a regression with areca controllers and older firmware versions

Without this fix an interrupt hits after the delayed work is canceled
and thus requeues it. So we end up freeing an armed timer.

It can be a problem when a pattern is loaded via the firmware interface.
LP55xx common driver has already locked the mutex in 'lp55xx_firmware_loaded()'.
So it should be deleted.
On the other hand, locks are required in store_engine_load()
on updating program memory.

commit 2feed5aecf5f367b92bd6b6e92afe9e3de466907 upstream.
The sysreg (system register) generates control signals for various blocks
like disp1blk, i2c, mipi, usb etc. However, it gets disabled as an unused
clock at boot-up. This can lead to failures in operation of above blocks,
because they can not be configured properly if this clock is disabled.
