From a896dc7a1f416e2b76efabff27c624c69645cc50 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Wed, 3 Sep 2014 15:30:41 -0300 Subject: [PATCH] [media] bt8xx: just return 0 instead of using a var Instead of allocating a var to store 0 and just return it, change the code to return 0 directly.
