2013-02-15staging/rtl8187se: Remove temporary variable for return valuePeter Huewe
The simple PlatformIORead1Byte function doesn't need to store its return value in a temporary variable; rather simply return the value directly. By moving the function to the top we can also get rid of the forward declaration. The wrapper functions could be easily replaced by direct calls to read_nic_byte but is kept for readability. Since this functions is local only we can mark it as static. Signed-off-by: Peter Huewe <peterhuewe@gmx.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-02-15staging/rtl8187se: Reuse ReadBBPortUchar to avoid duplicated codePeter Huewe
WriteBBPortUchar reimplements ReadBBPortUchar in its body, so we can remove the duplicated code by calling ReadBBPortUchar directly. Unfortunately we have to move ReadBBPortUchar around; while at it we can also get rid of the temporary variable for the return value. Also we can remove the local variables UCharData and RegisterContent in WriteBBPortUchar as they are not used / without effect. Both functions are only 'local' so we can mark them as static.

I don't know what this does, but I know that it doesn't reset the digital outputs as I've tried it. Since the hardware does not have any way to query the current output values and there is only the one command to update all the analog and digital outputs simultaneously (VMK8055_CMD_WRT_AD), send this command during initialization to set all the analog and digital outputs to a known state.

In vmk80xx_do_insn_bits the local variable reg, which is used as an index to the tx_buf array, can be used uninitialized if - data[0] == 0 and - devpriv->model != VMK8061_MODEL -> we get into the else branch without having reg initialized. Since the driver usually differentiates between VMK8061_MODEL and VMK8055_MODEL it's safe to assume that VMK8055_DO_REG was meant as an initial value. And to avoid duplication we can move the assignments to the top.

2013-02-11staging/zcache: Fix/improve zcache writeback code, tie to a config optionDan Magenheimer
It was observed by Andrea Arcangeli in 2011 that zcache can get "full" and there must be some way for compressed swap pages to be (uncompressed and then) sent through to the backing swap disk. A prototype of this functionality, called "unuse", was added in 2012 as part of a major update to zcache (aka "zcache2"), but was left unfinished due to the unfortunate temporary fork of zcache. This earlier version of the code had an unresolved memory leak and was anyway dependent on not-yet-upstream frontswap and mm changes. The code was meanwhile adapted by Seth Jennings for similar functionality in zswap (which he calls "flush"). Seth also made some clever simplifications which are herein ported back to zcache. As a result of those simplifications, the frontswap changes are no longer necessary, but a slightly different (and simpler) set of mm changes are still required [1]. The memory leak is also fixed. Due to feedback from akpm in a zswap thread, this functionality in zcache has now been renamed from "unuse" to "writeback". Although this zcache writeback code now works, there are open questions as how best to handle the policy that drives it. As a result, this patch also ties writeback to a new config option. And, since the code still depends on not-yet-upstreamed mm patches, to avoid build problems, the config option added by this patch temporarily depends on "BROKEN"; this config dependency can be removed in trees that contain the necessary mm patches.

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: "4th set of IIO new drivers cleanups and fixes for the 3.9 cycle + a new spi helper function. 1) Introduce spi_sync_transfer and use it within IIO. Originally it was envisioned that this nice little boilerplate replacement would go through the spi tree, but Grant Likely stated he'd prefer we take it through IIO as the example usecases were all in IIO (and are also in this pull request). Note that given their may have been some unresolved elements related to the coccinelle element of the patch, that has been stripped out and will doubtlessly follow at a later date (along with lots of other patches for drivers elsewhere in the tree). 2) New Invensense MPU6050 driver. This is stripped down to pretty much the basics from the original submission with the intent to build up all the fancy bits in an incremental (and hence reviewable fashion). It's been through a good few revisions so nice to finally merge this. 3) Change to iio_channel_get api to simplify device tree based mappings. The actual mappings are currently under review. 4) Build fixes for !CONFIG_IIO_TRIGGER in the st_sensors driver. This one snuck past during review and testing but got picked up by Randy Dunlap in a randconfig build. 5) Some max1363 cleanups and enhancements. 6) Some comment fixes to make them coherent and comprehensible. 7) Trivial build warning fix in mxs-lradc"

Prefix the functions in dgrp_specproc.c to avoid ambiguity in backtraces, such as the "info_proc_open" in this one: unreferenced object 0xffff88003b6696e0 (size 32): comm "cat", pid 2321, jiffies 4294705179 (age 29.434s) hex dump (first 32 bytes): 40 79 1c 81 ff ff ff ff 60 79 1c 81 ff ff ff ff @y......`y...... 50 79 1c 81 ff ff ff ff b0 62 89 81 ff ff ff ff Py.......b...... backtrace: [<ffffffff81c7e3b1>] kmemleak_alloc+0x21/0x50 [<ffffffff811955cb>] kmem_cache_alloc_trace+0x11b/0x190 [<ffffffff811c87dc>] single_open+0x3c/0xc0 [<ffffffff81896495>] info_proc_open+0x15/0x20 [<ffffffff8120c6d7>] proc_reg_open+0xb7/0x160 [<ffffffff811a1a5c>] do_dentry_open+0x1cc/0x280 [<ffffffff811a296a>] finish_open+0x4a/0x60 [<ffffffff811b14d7>] do_last+0xb07/0xdb0 [<ffffffff811b1842>] path_openat+0xc2/0x4f0 [<ffffffff811b1cac>] do_filp_open+0x3c/0xa0 [<ffffffff811a2dcc>] do_sys_open+0x11c/0x1c0 [<ffffffff811a2e8c>] sys_open+0x1c/0x20 [<ffffffff81ca3d69>] system_call_fastpath+0x16/0x1b [<ffffffffffffffff>] 0xffffffffffffffff Signed-off-by: Tommi Rantala <tt.rantala@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-02-08staging: dgrp: use correct release op for /proc/dgrp/infoTommi Rantala
Trinity (the syscall fuzzer) discovered that reading /proc/dgrp/info was leaking some memory. Fix by using the correct release op in info_proc_file_ops. unreferenced object 0xffff88003b6696e0 (size 32): comm "cat", pid 2321, jiffies 4294705179 (age 29.434s) hex dump (first 32 bytes): 40 79 1c 81 ff ff ff ff 60 79 1c 81 ff ff ff ff @y......`y...... 50 79 1c 81 ff ff ff ff b0 62 89 81 ff ff ff ff Py.......b...... backtrace: [<ffffffff81c7e3b1>] kmemleak_alloc+0x21/0x50 [<ffffffff811955cb>] kmem_cache_alloc_trace+0x11b/0x190 [<ffffffff811c87dc>] single_open+0x3c/0xc0 [<ffffffff81896495>] info_proc_open+0x15/0x20 [<ffffffff8120c6d7>] proc_reg_open+0xb7/0x160 [<ffffffff811a1a5c>] do_dentry_open+0x1cc/0x280 [<ffffffff811a296a>] finish_open+0x4a/0x60 [<ffffffff811b14d7>] do_last+0xb07/0xdb0 [<ffffffff811b1842>] path_openat+0xc2/0x4f0 [<ffffffff811b1cac>] do_filp_open+0x3c/0xa0 [<ffffffff811a2dcc>] do_sys_open+0x11c/0x1c0 [<ffffffff811a2e8c>] sys_open+0x1c/0x20 [<ffffffff81ca3d69>] system_call_fastpath+0x16/0x1b [<ffffffffffffffff>] 0xffffffffffffffff Signed-off-by: Tommi Rantala <tt.rantala@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
