From ee67674a7758dddc6abad16182b832a6a13b9ef9 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Wed, 30 Jul 2014 11:17:46 -0300 Subject: [PATCH] [media] xc5000: always write at dmesg when it fails to upload firmware On a normal condition, no errors should happen at xc5000 firmware upload is done. So, print at the dmesg if something bad happens.
