clang static analysis reports this problem
tuner-simple.c:714:13: warning: Assigned value is
garbage or undefined
buffer[1] = buffer[3];
^ ~~~~~~~~~
In simple_set_radio_freq buffer[3] used to be done
in-function with a switch of tuner type, now done
by a call to simple_radio_bandswitch which has this case
case TUNER_TENA_9533_DI:
case TUNER_YMEC_TVF_5533MF:
tuner_dbg("This tuner doesn't ...
return 0;
which does not set buffer[3]. In the old logic, this case
would have returned 0 from simple_set_radio_freq.
Recover this old behavior by returning an error for this
codition. Since the old simple_set_radio_freq behavior
returned a 0, do the same.

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.
