From c2286cc02e32a2f40735e42c27acecd60a91f060 Mon Sep 17 00:00:00 2001 From: Sakari Ailus Date: Mon, 26 Nov 2018 06:07:29 -0500 Subject: media: v4l: ioctl: Allow drivers to fill in the format description The v4l_fill_fmtdesc() function does a good job in filling in pixelformat description. While generally all drivers should depend on this function doing the job, staging drivers that use their own formats may not. Allow staging drivers to fill in their own formats by checking whether the description begins with a non-nil character before issuing the warning.
