[PATCH 0/1][Precise] UBUNTU: (pre-stable): bcma: add ext PA workaround for BCM4331 and BCM43431

[Seth Forshee]

This fix just hit Linus's tree, so quantal will get it in the rebase to
3.5-rc3. This is the backport for precise.

== SRU Justification ==

Impact: Macbook Pro models with BCM4331 wireless will be unable to
transmit wireless data following S3 if resumed without external power
attached.

Fix: Add workaround to BCMA to reinitialize the ext_pa pin muxings after
S3.

Test case: Suspend an affected machine, then resume it without A/C
power.  Observe that without this patch the wireless fails to work
afterwards, whereas with the patch the wireless does work.
