[PATCH 12/15] ASoC: mediatek: mt8192: Propagate mt8192_afe_gpio_request() errors in ADDA DAI

[phucduc . bui]

From: bui duc phuc <phucduc.bui@xxxxxxxxx>

Currently, DAPM event handlers in mt8192-dai-adda.c ignore the return
value of mt8192_afe_gpio_request(). If GPIO configuration fails during
PRE_PMU or POST_PMD events, the error is silently ignored.

Fix this by checking and propagating error codes from
mt8192_afe_gpio_request() in all ADDA DAPM event handlers.

Fixes: 607ac4859564 ("ASoC: mediatek: mt8192: support adda in platform driver")
