[PATCH 2/2] ASoC: codecs: rt5659: propagate GPIO errors

[phucduc.bui@gmail.com]

From: bui duc phuc <phucduc.bui@gmail.com>

devm_gpiod_get_optional() may return an error pointer, including
-EPROBE_DEFER, but rt5659_i2c_probe() does not handle these errors
for the ldo1-en GPIO and does not check for errors for the reset GPIO.

Check the return values and propagate GPIO lookup errors.

Fixes: d3cb2de2479b ("ASoC: rt5659: add rt5659 codec driver")
