From: Petr Mladek <pmladek@suse.com>

commit c3fee60908db4a8594f2e4a2131998384b8fa006 upstream.

The commit 97f5f0cd8cd0a0544 ("Input: implement SysRq as a separate input
handler") added pr_fmt() definition. It caused a duplicated message
prefix in the sysrq header messages, for example:

[ 177.053931] sysrq: SysRq : Show backtrace of all active CPUs
[ 742.864776] sysrq: SysRq : HELP : loglevel(0-9) reboot(b) crash(c)

Fixes: 97f5f0cd8cd0a05 ("Input: implement SysRq as a separate input handler")
