The patch regulator: core: Drop lockdep annotation in drms_uA_update()
has been applied to the regulator tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator.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 c407438f8795e6b403674b51fbdf5b3d66f811a4 Mon Sep 17 00:00:00 2001 From: Niklas Cassel <niklas.cas...@linaro.org> Date: Mon, 18 Feb 2019 20:29:14 +0100 Subject: [PATCH] regulator: core: Drop lockdep annotation in drms_uA_update() commit e5e21f70bfd3 ("regulator: core: Take lock before applying system load") took the regulator lock before calling drms_uA_update() in order to silence a lockdep warning during regulator_register(). However, we are not supposed to need locks at this point as the regulator is in the process of being registered, so there should be no possibility of concurrent access. Instead, remove the unnecessary locking and simply drop the lockdep annotation, since it is no longer valid.
