Subject: [PATCH -next]  ASoC: amd: acp3x: Fix return value check in acp3x_dai_probe()

In case of error, the function devm_ioremap() returns NULL pointer not
ERR_PTR(). The IS_ERR() test in the return value check should be
replaced with NULL test.

Fixes: c9fe7db6e884 ("ASoC: amd: Refactoring of DAI from DMA driver")
