Subject: drm: omapdrm: omap_crtc_flush() isn't called with modeset locked
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=55613acf1d1e4e6511e85d823e9235941236e6d3;p=linux.git

drm: omapdrm: omap_crtc_flush() isn't called with modeset locked

When performing asynchronous atomic updates the modeset lock isn't taken
around the callers of omap_crtc_flush(). This isn't an issue though, as
access to the CRTC is properly serialized. Just drop the warning.
