SCSI: enclosure: fix WARN_ON in dual path device removing

2013-12-12T06:37:53Z

commit a1470c7bf3a4676e62e4c0fb204e339399eb5c59 upstream. Bug report from: wenxiong@linux.vnet.ibm.com The issue is happened in dual controller configuration. We got the sysfs warnings when rmmod the ipr module. enclosure_unregister() in drivers/msic/enclosure.c, call device_unregister() for each componment deivce, device_unregister() ->device_del()->kobject_del() ->sysfs_remove_dir(). In sysfs_remove_dir(), set kobj->sd = NULL. For each componment device, enclosure_component_release()->enclosure_remove_links()->sysfs_remove_link() in which checking kobj->sd again, it has been set as NULL when doing device_unregister. So we saw all these sysfs WARNING. Tested-by: wenxiong@linux.vnet.ibm.com Signed-off-by: James Bottomley Signed-off-by: Greg Kroah-Hartman

mei: nfc: fix memory leak in error path

2013-11-29T19:28:09Z

commit 4bff7208f332b2b1d7cf1338e50527441283a198 upstream. The flow may reach the err label without freeing cl and cl_info cl and cl_info weren't assigned to ndev->cl and cl_info so they weren't freed in mei_nfc_free called on error path Cc: Samuel Ortiz Signed-off-by: Tomas Winkler Signed-off-by: Greg Kroah-Hartman

lkdtm: isolate stack corruption test

2013-11-29T19:27:56Z

commit 629c66a22c21b692b6e58b9c1d8fa56a60ccb52d upstream. When tests were added to lkdtm that grew the stack frame, the stack corruption test stopped working. This isolates the test in its own function, and forces it not to be inlined. Signed-off-by: Kees Cook Fixes: cc33c537c12f ("lkdtm: add "EXEC_*" triggers") Signed-off-by: Greg Kroah-Hartman

misc: atmel_pwm: add deferred-probing support

2013-11-20T20:37:36Z

commit 5c6d6fd1564138ad048564e48639f842714a90c6 upstream. Two drivers (atmel-pwm-bl and leds-atmel-pwm) currently depend on the atmel_pwm driver to have bound to any pwm-device before their devices are probed. Support deferred probing of such devices by making sure to return -EPROBE_DEFER from pwm_channel_alloc when no pwm-device has yet been bound.

mei: cancel stall timers in mei_reset

2013-09-26T20:56:53Z

Unset init_clients_timer and amthif_stall_timers in mei_reset in order to cancel timer ticking and hence avoid recursive reset calls. Cc: # 3.9+ Signed-off-by: Alexander Usyskin Signed-off-by: Tomas Winkler Signed-off-by: Greg Kroah-Hartman

mei: bus: stop wait for read during cl state transition

2013-09-26T20:56:53Z

Bus layer omitted check for client state transition while waiting for read completion The client state transition may occur for example as result of firmware initiated reset Add mei_cl_is_transitioning wrapper to reduce the code repetition.: Cc: # 3.9+ Signed-off-by: Tomas Winkler Signed-off-by: Greg Kroah-Hartman

mei: make me client counters less error prone

2013-09-26T20:56:53Z

1. u8 counters are prone to hard to detect overflow: make them unsigned long to match bit_ functions argument type 2. don't check me_clients_num for negativity, it is unsigned. 3. init all the me client counters from one place Cc: # 3.9+ Signed-off-by: Tomas Winkler Signed-off-by: Greg Kroah-Hartman

Remove GENERIC_HARDIRQ config option

2013-09-13T13:09:52Z

After the last architecture switched to generic hard irqs the config options HAVE_GENERIC_HARDIRQS & GENERIC_HARDIRQS and the related code for !CONFIG_GENERIC_HARDIRQS can be removed. Signed-off-by: Martin Schwidefsky
