Both snd_ctl_add() and snd_ctl_replace() process the things in a fairly similar way, and indeed the most of the codes can be unified. This patch is a refactoring to consolidate the both functions to call a single helper with an extra "mode" argument. There should be no functional difference, except for one additional sanity check applied now to snd_ctl_replace() (which was rather overlooking, IMO), too. Signed-off-by: Takashi Iwai <tiwai@suse.de>
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.
