Subject: [PATCH -mm 0/5] b43: Fix suspend/resume deadlock
Date: Fri, 25 Jan 2008 01:27:20 +0100	[thread overview]
Message-ID: <200801250127.21966.rjw@sisk.pl> (raw)

Hi,

The following series of patches is intended to fix the suspend/resume deadlock
occuring as a result of unregistering device objects, locked by the PM core,
during suspend/resume cycles by the b43 driver.

In short, the b43 driver is modified to avoid unregistering device objects
during suspend/resume cycles except for the resume code path, in which the
devices are unregistered using the recently introduced suspend-safe method.
For this purpose, it is necessary to introduce the possibility to safely remove
misc devices, leds classdevs and hwrng devices during suspend/resume cycles
(patches 2/5, 4/5, 3/5, respectively).

Please consider for applying.

Thanks,
Rafael
