[PATCH 00/11] ALSA: Make control API taking controls_rwsem consistently

by Takashi Iwai

A few ALSA control API helpers like snd_ctl_rename(), snd_ctl_remove() and snd_ctl_find_*() suppose the callers taking card->controls_rwsem. But it's error-prone and fragile. This patch set tries to change those API functions to take the card->controls>rwsem internally by themselves, so that the drivers don't need to take care of lockings. After applying this patch set, only a couple of places still touch card->controls_rwsem (which are OK-ish as they need for traversing the control linked list).

[PATCH] staging: Explicitly include correct DT includes

by Rob Herring

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.
