Date: Fri, 14 Aug 2015 19:16:31 -0700 From: Mark Brown <broonie@...nel.org> To: Markus Pargmann <mpa@...gutronix.de>, Mark Brown <broonie@...nel.org> Cc: linux-kernel@...r.kernel.org Subject: Applied "regmap: Fix regmap_can_raw_write check" to the regmap tree The patch regmap: Fix regmap_can_raw_write check has been applied to the regmap tree at git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap.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 07ea400e1b26726f21b2c2299d187d6eb7eb4324 Mon Sep 17 00:00:00 2001 From: Markus Pargmann <mpa@...gutronix.de> Date: Wed, 12 Aug 2015 12:12:33 +0200 Subject: [PATCH] regmap: Fix regmap_can_raw_write check This function is missing a check if map->bus->write is implemented. If it is not implemented arbitrary raw writes are not possible.
