[1/1] Input: wm97xx: Simplify resource management commit: a4f399a1416f645ac701064a55b0cb5203707ac9 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

Since the commit in the Fixes tag below, 'wm->input_dev' is a managed resource that doesn't need to be explicitly unregistered or freed (see devm_input_allocate_device() documentation) So, remove some unless line of code to slightly simplify it.
