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.
