From 642ac63d166d07e43396a4d8c48ab24cb072cb18 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Tue, 11 Jun 2019 10:02:43 -0400 Subject: [PATCH] media: drivers/staging/media: don't set description for ENUM_FMT The V4L2 core sets the format description and flags for the driver in order to ensure consistent naming. So drop the strscpy of the description in drivers. Also remove any description strings in driver-internal structures since those are no longer needed. Note that bcm2835-camera.c: the formats array still stores the flags field for compressed formats since that information is used elsewhere in the driver. But enum_fmt doesn't use it anymore, since the core will set the COMPRESSED flag correctly.
