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 f1013cdeeeb978e3d8ef254bee1f007da4c862f3 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Tue, 28 Feb 2017 15:43:43 +0100 Subject: [PATCH] ASoC: ux500: drop platform DAI assignments This platform is completely probed by device tree nowadays, so we need to do a bigger cleanup removing all the non-DT codepaths. This cleanup must however go in as a fix since it fixes a regression. Currently when Ux500 audio is enabled, dmesg complains like this: entry->name == "prealloc" entry->name == "prealloc_max" entry->name == "prealloc" ------------[ cut here ]------------ WARNING: CPU: 0 PID: 95 at ../fs/proc/generic.c:346 proc_register+0xf0/0x110 proc_dir_entry 'sub0/prealloc' already registered (...) entry->name == "prealloc_max" ------------[ cut here ]------------ WARNING: CPU: 0 PID: 95 at ../fs/proc/generic.c:346 proc_register+0xf0/0x110 proc_dir_entry 'sub0/prealloc_max' already registered (...) snd-soc-mop500 soc:sound: ab8500-codec-dai.0 <-> 80124000.msp mapping ok entry->name == "prealloc" entry->name == "prealloc_max" entry->name == "prealloc" ------------[ cut here ]------------ WARNING: CPU: 0 PID: 95 at ../fs/proc/generic.c:346 proc_register+0xf0/0x110 proc_dir_entry 'sub0/prealloc' already registered (...) entry->name == "prealloc_max" ------------[ cut here ]------------ WARNING: CPU: 0 PID: 95 at ../fs/proc/generic.c:346 proc_register+0xf0/0x110 proc_dir_entry 'sub0/prealloc_max' already registered snd-soc-mop500 soc:sound: ab8500-codec-dai.1 <-> 80125000.msp mapping ok This is because PCMs are created twice for the same hardware, and this happens because both "platform" and "CPU" DAI links are specified. But platform/CPU is an either/or pair, not a both/and pair. This has maybe worked in the past, but it is causing trouble now, so let us begin the cleanups by removing the platform assignment and silencing the boot noise, and make a proper DT cleanup for the next kernel cycle.
