From 98c1ce0ccff1617cba45e8ead236768a50545e7f Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Fri, 23 Mar 2018 07:51:07 -0400 Subject: media: cec-core: fix a bug at cec_error_inj_write() If the adapter doesn't have error_inj_parse_line() ops, the write() logic won't return -EINVAL, but, instead, it will keep looping, because "count" is a non-negative number.
