Subject: [PATCH 03/33] vt: might_sleep() annotation for do_blank_screen
Date: Mon, 20 May 2019 10:21:46 +0200	[thread overview]
Message-ID: <20190520082216.26273-4-daniel.vetter@ffwll.ch> (raw)
In-Reply-To: <20190520082216.26273-1-daniel.vetter@ffwll.ch>

For symmetry reasons with do_unblank_screen, except without the
oops_in_progress special case.

Just a drive-by annotation while I'm trying to untangle the fbcon vs.
fbdev screen blank/unblank maze.
