Subject: [PATCH] ASoC: codecs: fix the right check and simplify code

In the file drivers/base/platform.c, the return description of
platform_get_irq is 'non-zero IRQ number on success, negative
error number on failure.', so the check is wrong, fix it. And
when get irq failed, the function platform_get_irq logs an error
message.

Fixes: 5e2404493f9f ("ASoC: codecs: add MT6357 support")
