The patch ASoC: ab8500: add range to usleep_range
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 45a310136b3ed52267e757c57e835f583140aa5f Mon Sep 17 00:00:00 2001 From: Nicholas Mc Guire <hof...@opentech.at> Date: Sun, 7 Apr 2019 04:59:34 +0200 Subject: [PATCH] ASoC: ab8500: add range to usleep_range Providing a range for usleep_range() allows the hrtimer subsystem to coalesce timers - as this delay has no upper limit anyway (interrupts or context switch is possible) it should not hurt to extend this from 2 to 2-4 milliseconds.
