Subject[PATCH -next] ASoC: rt700: fix return value check in rt700_sdw_probe()
Date
In case of error, the function devm_regmap_init() returns ERR_PTR() and
never returns NULL. The NULL test in the return value check should be
replaced with IS_ERR().

Fixes: 7d2a5f9ae41e ("ASoC: rt700: add rt700 codec driver")
