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 b413886886b9a8f845f7d1a5adafa0ca573d3828 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Mon, 19 Sep 2016 21:30:25 +0200 Subject: [PATCH] ASoC: fsl_asrc: use flat regmap cache Same as commit ce492b3b8f99cf9d2f807ec22d8805c996a09503 Subject: drm/fsl-dcu: use flat regmap cache Using flat regmap cache instead of RB-tree to avoid the following lockdep warning on driver load: WARNING: CPU: 0 PID: 1 at kernel/locking/lockdep.c:2871 lockdep_trace_alloc+0x104/0x128 DEBUG_LOCKS_WARN_ON(irqs_disabled_flags(flags)) The RB-tree regmap cache needs to allocate new space on first writes. However, allocations in an atomic context (e.g. when a spinlock is held) are not allowed. The function regmap_write calls map->lock, which acquires a spinlock in the fast_io case. Since the driver uses MMIO, the regmap bus of type regmap_mmio is being used which has fast_io set to true.
