[ Upstream commit 592ab3936b096da5deb64d4c906edbeb989174d6 ]
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.
