The patch regulator: core: Add regulator_is_equal() helper has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git 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 >From b059b7e0ec3208ff1e17cff6387d75a9fbab4e02 Mon Sep 17 00:00:00 2001 From: Marek Vasut <marex@xxxxxxx> Date: Fri, 20 Dec 2019 17:44:49 +0100 Subject: [PATCH] regulator: core: Add regulator_is_equal() helper Add regulator_is_equal() helper to compare whether two regulators are the same. This is useful for checking whether two separate regulators in a driver are actually the same supply.
