[PATCH v4 04/10] ASoC: tas2764: Reinit cache on part reset

[James Calligeros]

From: Martin Povišer <povik+lin@xxxxxxxxxxx>

When the part is reset in component_probe, do not forget to reinit the
regcache, otherwise the cache can get out of sync with the part's
actual state. This fix is similar to commit 0a0342ede303
("ASoC: tas2770: Reinit regcache on reset") which concerned the
tas2770 driver.

Fixes: 827ed8a0fa50 ("ASoC: tas2764: Add the driver for the TAS2764")
