ASoC: cs43130: Fix possible Oops with invalid dev_id
As compiler spotted out, there is the potential NULL-dereference in the code when dc-measure OF is given for other than 43130/43131: sound/soc/codecs/cs43130.c:2089:18: warning: ‘hpload_seq’ may be used uninitialized in this function [-Wmaybe-uninitialized] Warn it and return before triggering Oops. Fixes: 8f1e5bf9b440 ("ASoC: cs43130: Add support for CS43130 codec") Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Mark Brown <broonie@kernel.org>
