[1/1] ASoC: rockchip-i2s: Undo BCLK pinctrl changes commit: 1e347f861da8ddb17e1d1b3113cb6c188e0de3e5 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

The version of the BCLK pinctrl management changes that made it into v5.19 has caused problems on some systems due to overly strict DT requirements but attempts to fix it have caused further breakage on other platforms. Just drop the changes for this release, we already have a better version queued for -next. Fixes: 26b9f2fa7b1c ("ASoC: rockchip: i2s: Fix NULL pointer dereference when pinctrl is not found") Fixes: a5450aba737d ("ASoC: rockchip: i2s: switch BCLK to GPIO") Signed-off-by: Mark Brown <broonie@kernel.org> --- sound/soc/rockchip/rockchip_i2s.c | 163 ++++++------------------------ 1 file changed, 31 insertions(+), 132 deletions(-)
