2011-09-06staging: hv: fix a kernel warning in netvsc_linkstatus_callback()Haiyang Zhang
netif_notify_peers() caused a kernel warning in netvsc_linkstatus_callback(), because netvsc_linkstatus_callback() is within IRQ context. So we move the first call to netif_notify_peers() into queued work as well, but with zero delay. In addition to "staging-next", this should also be back-ported to stable kernels 2.6.32 and later.

2011-09-06Staging: hv: vmbus: Cleanup the code in process_chn_event()K. Y. Srinivasan
A channel in Hyper-V is equivalent to a device. Thus, a channel is persistent once it is presented to the guest, even if the driver managing this device is unloaded. By checking and invoking the driver specific callback function under the protection of the channel inbound_lock, we can properly deal with racing driver unloads since an unloading driver sets the callback to NULL under the protection of this inbound_lock.

2011-09-06staging: lirc_sasem: fix NULL pointer dereference in sasem_probeAlexey Khoroshilov
If any memory allocation failed, goto alloc_status_switch leads to mutex_unlock(&context->ctx_lock) while context is NULL.

2011-09-06staging: xgifb: fix LVDS LCD resolution data setupAaro Koskinen
If the driver fails to get LVDS LCD data from the firmware, it falls back to using driver's hardcoded values. However, this is done too early in the probe. The selected video mode index is not yet known, and also in some cases it could be defaulting to -1 resulting in a read outside the array. Fix this by moving the array lookup after the video mode validation.
