The patch regulator: pwm: Don't warn on probe deferral 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 0cd71b9a43ad80f4d9a8bfde6ec6db8daf447029 Mon Sep 17 00:00:00 2001 From: Jon Hunter <jonathanh@xxxxxxxxxx> Date: Mon, 2 Mar 2020 14:14:28 +0000 Subject: [PATCH] regulator: pwm: Don't warn on probe deferral Deferred probe is an expected return value for devm_pwm_get(). Given that the driver deals with it properly, rather than warn on probe deferral, only output a message on probe deferral if debug level prints are enabled.
