[2/2] regulator: don't compare raw GPIO descriptor pointers commit: aaf6223ea2a1ff9316a81bf851fd5a0e82635b60 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
Handling of shared GPIOs in the kernel needs some improvements. Let's start with a simple change of not comparing GPIO descriptor pointers directly as there's nothing that guarantees that the same physical pin will always be represented by a single GPIO descriptor obtained by calling gpiod_get(). For merging: I suggest to take patch 1/2 through the GPIO tree and provide an immutable tag for the regulator tree.
