Subject: [PATCH 5.15.y 02/14] ARM: spear: Do not use timer namespace for timer_shutdown() function

From: "Steven Rostedt (Google)" <rostedt@...dmis.org>

[ Upstream commit 80b55772d41d8afec68dbc4ff0368a9fe5d1f390 ]

A new "shutdown" timer state is being added to the generic timer code. One
of the functions to change the timer into the state is called
"timer_shutdown()". This means that there can not be other functions called
"timer_shutdown()" as the timer code owns the "timer_*" name space.

Rename timer_shutdown() to spear_timer_shutdown() to avoid this conflict.
