has been applied to the asoc tree at

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.

From: Cheng-Yi Chiang cychiang@chromium.org Date: Fri, 16 Nov 2018 17:28:56 +0800 Subject: [PATCH] ASoC: rt5663: Fix error handling of regulator_set_load
The default implementation of regulator_set_load returns REGULATOR_MODE_NORMAL, which is positive. [This was a bug which is being fixed but the change is valid anyway -- bronie]
rt5663_i2c_probe should only do error handling when return value of regulator_set_load is negative. In this case, rt5663_i2c_probe should return error.
Also, consolidate err_irq into err_enable.
Fix the missing goto for temporary regmap and rt5663->regmap.
