6.6-stable review patch. If anyone has any objections, please let me know. ------------------ From: Richard Fitzgerald <rf@xxxxxxxxxxxxxxxxxxxxx> [ Upstream commit 73580ec607dfe125b140ed30c7c0a074db78c558 ] Adds calls to disable regmap cache-only after a successful return from cs35l56_wait_for_firmware_boot(). This is to prepare for a change in the shared ASoC module that will leave regmap in cache-only mode after cs35l56_system_reset(). This is to prevent register accesses going to the hardware while it is rebooting.
