Subject: ALSA: hda - Remove pre_resume and post_suspend ops
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=607d4f7f0551eb591fbaca4bf44a8d6251e82f00;p=linux-beck.git

ALSA: hda - Remove pre_resume and post_suspend ops

Since the recent commit, the resume procedure is always performed at
the resume time.  This makes the pre_resume hack for VREF mute LED on
some HP laptops superfluous.  As this is the only user of pre_resume
(and there is no user of post_suspend) ops, let's kill them again.
