Subject[PATCH] drm/radeon: A gray screen appears when going into hibernation(S4)
Date
Radeon Card:
Caicos[Radeon HD 6450/7450/8450 /R5 230 OEM]

there is no gray screen when echo 4>/sys/module/drm/parameters/debug,
so the WREG32 function after DRM_DEBUG_KMS may have wrong when going
into hibernation.the delay of msleep(50) just can fix gray screen.
