SubjectRe: [PATCH V2 2/2] apple_gmux: Add support for newer hardware
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Only in relation to Seth's future apple-gmux patch series about
vgaswitcheroo and restoring the gmux device configuration across
suspend/resume [1]:
On resume the gmux registers 0x28 (DDC) and 0x10 (SWITCH_DISPLAY)
(i.e., the first two writes) are not restored (result: the screen
remains black after suspend/resume).

Of course, this does not happen with my patch proposal ;)
Unfortunately, I have not the time to sort this out in the next couple
of days -- on the other hand this is probably not a problem w.r.t.
this patch, but needs to be taken care of in Seth's patch series.
