The patch regulator: axp20x: remove a redundant null check on rdev
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 ea7b971cd64b45c6be08c02e14d30ec3c9a5b336 Mon Sep 17 00:00:00 2001 From: Colin Ian King <[email protected]> Date: Fri, 15 Feb 2019 09:45:54 +0000 Subject: [PATCH] regulator: axp20x: remove a redundant null check on rdev Currently rdev is dereferenced when assigning desc before rdev is null checked, this is leading to static analysis warnings. However, rdev can never be null, so the null check is redundant and can be removed.
