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

From: Daniel Mack daniel@zonque.org
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.
