SAEximRunCond expanded to false X-PTX-Original-Recipient: linux-usb@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-usb@vger.kernel.org Since we have the helper function v4l2_fill_fmtdesc, we can use this to get the corresponding descriptive string for the pixelformat and set the compressed flag. This patch is removing the redundant name field in uvc_format_desc and makes use of v4l2_fill_fmtdesc instead.
