Subject: [PATCH] rtl8192{ce,cu,de,se}: avoid problems because of possible ERFOFF -> ERFSLEEP -> .. transition
Date: Tue, 06 Dec 2011 22:15:12 -0600 [thread overview]
Message-ID: <4EDEE850.4040508@lwfinger.net> (raw)
From: Philipp Dreimann <philipp@dreimann.net>
In drivers rtl8192ce, rtl8192cu, rtl8192se, and rtl8192de, missing break
statements would allow ppsc->rfpwr_state to be changed to ERFSLEEP even though
the device is actually in ERFOFF.

John,
I have not heard anything from Chaoming, but this code certainly looks wrong.
Please apply to 3.2 if possible.
Larry
