[PATCH 4.14 03/36] ASoC: sta32x: set ->component pointer in private struct

[Greg Kroah-Hartman]

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

commit 747df19747bc9752cd40b9cce761e17a033aa5c2 upstream

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.")
