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).

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
