The passed parameter to sysrq handlers is a key (a character). So change the type from 'int' to 'u8'. Let it specifically be 'u8' for two reasons: * unsigned: unsigned values come from the upper layers (devices) and the tty layer assumes unsigned on most places, and * 8-bit: as that what's supposed to be one day in all the layers built on the top of tty. (Currently, we use mostly 'unsigned char' and somewhere still only 'char'. (But that also translates to the former thanks to -funsigned-char.))

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.
