Subject: [PATCH] media: dvb: return -EREMOTEIO on i2c transfer failure.
Date: Mon, 10 Feb 2020 17:51:33 +0000 [thread overview]
Message-ID: <20200210175133.479739-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
Currently when i2c transfers fail the error return -EREMOTEIO
is assigned to err but then later overwritten when the tuner
attach call is made. Fix this by returning early with the
error return code -EREMOTEIO on i2c transfer failure errors.
Addresses-Coverity: ("Unused value")
Fixes: fbfee8684ff2 ("V4L/DVB (5651): Dibusb-mb: convert pll handling to properly use dvb-pll")
