Subject: [PATCH] ASoC: sta32x: set ->component pointer in private struct
The ESD watchdog code in sta32x_watchdog() dereferences the pointer
which is never assigned.
This is a regression from a1be4cead9b950 ("ASoC: sta32x: Convert to direct
regmap API usage.") which went unnoticed since nobody seems to use that ESD
workaround.
Fixes: a1be4cead9b950 ("ASoC: sta32x: Convert to direct regmap API usage.")
