H A D | rt5514.c | 0a78b248 Fri Apr 14 11:40:31 CDT 2017 Douglas Anderson <dianders@chromium.org> ASoC: rt5514: Avoid relying on uninitialized "val" value
In rt5514_i2c_probe() if the regmap_read(RT5514_VENDOR_ID2) fails then "val" may be left as uninitialized. Current code relies on "val" not being RT5514_DEVICE_ID, but that's potentially unsafe.
Let's check for errors from regmap_read() and also explicitly init the value do we're not passing a possibly uninitialized int to printk.
