Applied to https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-next Thanks! [1/1] ASoC: fsl_sai: Refine regcache usage with pm runtime commit: d8d702e19e997cf3f172487e0659d0e68aa5ede5 All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark

When there is dedicated power domain bound with device, after probing the power will be disabled, then registers are not accessible in fsl_sai_dai_probe(), so regcache only need to be enabled in end of probe() and regcache_mark_dirty should be moved to pm runtime resume callback function.
