From 222964eaf2472053221341c331eb81e87c8b04f2 Mon Sep 17 00:00:00 2001 From: Guennadi Liakhovetski Date: Tue, 8 May 2018 11:07:42 -0400 Subject: [PATCH] media: uvcvideo: Remove a redundant check Event subscribers cannot have a NULL file handle. They are only added at a single location in the code, and the .fh pointer is used without checking there.
