[PATCH 0/3] firmware: Fix usermodehelper deadlock at shutdown

[Takashi Iwai]

Hi,

this is a series of patches for the issue we faced in the firmware
loader code during debugging the problem with dell_rbu driver with
3.9 kernel.

The original problem was that the shutdown gets stuck when DELL BIOS
update is performed.  This turned out to be a problem in the firmware
loader.  Although the reason of dell_rbu driver breakage is still
unclear, we should fix the firmware loader side, at least, not to
stall during shutdown.


thanks,

Takashi
