Subject: [PATCH 19/21] drm: mxsfb: Turn mxsfb_set_pixel_fmt() into a void function
Date: Mon, 9 Mar 2020 21:52:14 +0200 [thread overview]
Message-ID: <20200309195216.31042-20-laurent.pinchart@ideasonboard.com> (raw)
In-Reply-To: <20200309195216.31042-1-laurent.pinchart@ideasonboard.com>
The mxsfb_set_pixel_fmt() function returns an error when the selected
pixel format is unsupported. This can never happen, as such errors are
caught by the DRM core. Remove the error check.
