Subject: drm: Remove crtc/connector->save/restore hooks
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=813b0f3e00d402279718403aeb621c965f97180e;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

drm: Remove crtc/connector->save/restore hooks

They're not how system suspend/resume should be done with atomic
(there's new helpers for that developed by Thierry Reding), and for
legacy drivers this really should be a helper hook and not a core one.

But there's not even helper code to use them, and only 2 drivers
(which now have their own private hooks) set them. Ditch them.

Saves me typing some kerneldoc, too ;-)
