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 892ccf0f2173a9ede5448411e9475616fb21fb51 Mon Sep 17 00:00:00 2001 From: Sylwester Nawrocki <s.nawrocki@samsung.com> Date: Tue, 25 Oct 2016 12:57:57 +0200 Subject: [PATCH] ASoC: s3c24xx_uda134x: Move global variables to driver's data structure Gather all driver's private variables in common data structure and allocate the data structure dynamically.
