2015-06-13misc: sram: fix enabled clock leak on error pathVladimir Zapolskiy
If devm_gen_pool_create() fails, the previously enabled sram->clk is not disabled on probe() exit. Because reserved block logic relies only on information from device tree, there is no need to get and enable device clock in advance, especially because not provided clock is not considered as an error, so it is safe to place devm_clk_get() at the end of probe(). No functional change. Signed-off-by: Vladimir Zapolskiy <vladimir_zapolskiy@mentor.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2015-06-12parport: check exclusive access before registerSudip Mukherjee
As of now we were starting the registration process and after the device is registered we were checking if the device can be used by the parport. Now lets check it first so that we do not need to go through the registration process only to fail at the end. The original exclusive access check at the end is still there so that we do not get any surprises if two different process registers its device with same parport and with exclusive access at the same time.

2015-06-03Merge tag 'extcon-next-for-4.2' of ↵Greg Kroah-Hartman
git://git.kernel.org/pub/scm/linux/kernel/git/chanwoo/extcon into char-misc-next Chanwoo writes: Update extcon for v4.2 This patchset include the huge update of extcon core and add the new one extcon driver and fix minor isseu of extcon drivers. Detailed description for patchset: 1. Update the extcon core. - Modify the extcon device name on sysfs from device name name to 'extcon[X]' as following because if same extcon device are included in H/W development board, the one of the two device driver might be failed on the probe(). : /sys/class/extcon/[device name] -> /sys/class/extcon/extcon[X] - Use the unique id for external connectors instead of legacy string name. Previously, extcon used the string name to identify the type of external connectors. This way have the many potential issues. So, extcon core define the unique id for each external connectors as following: enum extcon { EXTCON_NONE = 0x0, /* USB external connector */ EXTCON_USB = 0x1, EXTCON_USB_HOST = 0x2, /* Charger external connector */ EXTCON_TA = 0x10, EXTCON_FAST_CHARGER = 0x11, EXTCON_SLOW_CHARGER = 0x12, EXTCON_CHARGE_DOWNSTREAM = 0x13, /* Audio and video external connector */ EXTCON_LINE_IN = 0x20, EXTCON_LINE_OUT = 0x21, EXTCON_MICROPHONE = 0x22, EXTCON_HEADPHONE = 0x23, ... }; - Update tye prototype of extcon_register_notifier() by using the unique id (enum extcon) of external connectors. - Add extcon_get_edev_name() API to get the name of extcon device on extcon client driver because the name is included in 'struct extcon_dev' and 'struct extcon_dev' should be handled in only drivers/extcon directory. So. if extcon client need the name of extcon device, they could use this function. - Unify the jig/dock and MHL-TA cable name on extcon driver. : JIG-{USB-ON|USB-OFF|UART-ON|UART-OFF} -> JIG : Dock-{Smart|Desk|Audio|Card} -> DOCK : MHL-TA -> TA - Use the capital letter for the name of all external connectors. - Remove the optional print_name() function pointer from struct extcon_dev to maintain the consistent name of extcon device. 2. Add the new extcon-axp288.c extcon driver. - The extcon-axp288.c driver support for AXP288 PMIC which has the BC1.2 charger detection capability. So this extcon driver can detect the EXTCON_SLOW_CHARGER, EXTCON_CHARGE_DOWNSTREAM and EXTCON_FAST_CHARGER. 3. Update the extcon-arizona.c driver. - Add support for selective detection mode when headphone detection. - Apply HP clamps for WM8280 4. Clean-up the extcon core and drivers. - Add manufactor information of each extcon device. - Fix checkpatch warning and minor coding style on extcon.c.c - Fix build break if GPIOLIB is not enabled on extcon-usb-gpiio.c. - Set the direction of gpio when calling devm_gpiod_get() on extcon-usb-gpio.c

Channels/sub-channels can be affinitized to VCPUs in the guest. Implement this affinity in a way that is NUMA aware. The current protocol distributed the primary channels uniformly across all available CPUs. The new protocol is NUMA aware: primary channels are distributed across the available NUMA nodes while the sub-channels within a primary channel are distributed amongst CPUs within the NUMA node assigned to the primary channel.

2015-05-31Drivers: hv: balloon: check if ha_region_mutex was acquired in ↵Vitaly Kuznetsov
MEM_CANCEL_ONLINE case Memory notifiers are being executed in a sequential order and when one of them fails returning something different from NOTIFY_OK the remainder of the notification chain is not being executed. When a memory block is being onlined in online_pages() we do memory_notify(MEM_GOING_ONLINE, ) and if one of the notifiers in the chain fails we end up doing memory_notify(MEM_CANCEL_ONLINE, ) so it is possible for a notifier to see MEM_CANCEL_ONLINE without seeing the corresponding MEM_GOING_ONLINE event. E.g. when CONFIG_KASAN is enabled the kasan_mem_notifier() is being used to prevent memory hotplug, it returns NOTIFY_BAD for all MEM_GOING_ONLINE events. As kasan_mem_notifier() comes before the hv_memory_notifier() in the notification chain we don't see the MEM_GOING_ONLINE event and we do not take the ha_region_mutex. We, however, see the MEM_CANCEL_ONLINE event and unconditionally try to release the lock, the following is observed: [ 110.850927] ===================================== [ 110.850927] [ BUG: bad unlock balance detected! ] [ 110.850927] 4.1.0-rc3_bugxxxxxxx_test_xxxx #595 Not tainted [ 110.850927] ------------------------------------- [ 110.850927] systemd-udevd/920 is trying to release lock (&dm_device.ha_region_mutex) at: [ 110.850927] [<ffffffff81acda0e>] mutex_unlock+0xe/0x10 [ 110.850927] but there are no more locks to release! At the same time we can have the ha_region_mutex taken when we get the MEM_CANCEL_ONLINE event in case one of the memory notifiers after the hv_memory_notifier() in the notification chain failed so we need to add the mutex_is_locked() check. In case of MEM_ONLINE we are always supposed to have the mutex locked. Signed-off-by: Vitaly Kuznetsov <vkuznets@redhat.com> Signed-off-by: K. Y.

2015-05-31char: misc: restore MISC_DYNAMIC_MINOR on device_create() failureVladimir Zapolskiy
On attempt to register a dynamic minor misc device its minor number is updated to a virtual minor number prior to device_create() call, however on error path misc->minor == MISC_DYNAMIC_MINOR is not restored. Following the rule of thumb that a function returning an error must not change the state of the caller, assign MISC_DYNAMIC_MINOR back. The problem is met in a sutuation, when subsys_initcall(misc_init) is not yet called and misc_class is not created, but misc_register() modifies statically defined ".minor = MISC_DYNAMIC_MINOR", therefore implicitly changing the client's logic on next attempt (e.g. retrying from deferred list) to register a misc device, whose minor number is converted from dynamic to some unknown static one.

2015-05-24hwmon: Allow to compile dell-smm-hwmon driver without /proc/i8kPali Rohár
This patch splits CONFIG_I8K compile option to SENSORS_DELL_SMM and CONFIG_I8K. Option SENSORS_DELL_SMM is now used to enable compilation of dell-smm-hwmon driver and old CONFIG_I8K option to enable /proc/i8k interface in driver. So this change allows to compile dell-smm-hwmon driver without legacy /proc/i8k interface which is needed only for old Dell Inspirion models or for userspace i8kutils package. For backward compatibility when CONFIG_I8K is enabled then also SENSORS_DELL_SMM is enabled and so driver dell-smm-hwmon (with /proc/i8k) is compiled.

2015-05-24Drivers: hv: vmbus: distribute subchannels among all vcpusVitaly Kuznetsov
Primary channels are distributed evenly across all vcpus we have. When the host asks us to create subchannels it usually makes us num_cpus-1 offers and we are supposed to distribute the work evenly among the channel itself and all its subchannels. Make sure they are all assigned to different vcpus. Signed-off-by: Vitaly Kuznetsov <vkuznets@redhat.com> Signed-off-by: K. Y.

2015-05-24Drivers: hv: vmbus: move init_vp_index() call to vmbus_process_offer()Vitaly Kuznetsov
We need to call init_vp_index() after we added the channel to the appropriate list (global or subchannel) to be able to use this information when assigning the channel to the particular vcpu. To do so we need to move a couple of functions around. The only real change is the init_vp_index() call. This is a small refactoring without a functional change.

2015-05-24Drivers: hv: vmbus: decrease num_sc on subchannel removalVitaly Kuznetsov
It is unlikely that that host will ask us to close only one subchannel for a device but let's be consistent. Do both num_sc++ and num_sc-- with channel->lock to be on the safe side.
