Subject: [PATCH][next] media: i2c: imx334: Fix a read of the uninitialized variable ret

From: Colin Ian King <colin.king@...onical.com>

Currently there is a dev_err error message that is printing the
error status in variable ret (that has not been set) instead of
the correct error status from imx334->reset_gpio.  Fix this.

Addresses-Coverity: ("Uninitialized scalar variable")
Fixes: 9746b11715c3 ("media: i2c: Add imx334 camera sensor driver")
