H A Dcs35l35.cdiff 8e71321d19c4ed02d9eed15955b8d485bab016fc Mon Mar 27 10:54:27 CDT 2017 Charles Keepax <ckeepax@opensource.wolfsonmicro.com> ASoC: cs35l35: Clear reset_gpio on the error path in probe

The error path in probe attempts to put the device back into reset.
Should we fail to get the reset_gpio (such as a probe defer) we will
leave the error value in there, which the gpiod_set_value_cansleep on
the error path will attempt to deference.

Fix this issue by clearing reset_gpio before we head into the error
path.
