cpufreq: amd-pstate: set varaiable mode_state_machine storage-class-specifier to static

[PATCH] cpufreq: amd-pstate: set varaiable mode_state_machine storage-class-specifier to static

Posted by Tom Rix 3 years ago

smatch reports
drivers/cpufreq/amd-pstate.c:907:25: warning: symbol
  'mode_state_machine' was not declared. Should it be static?

This variable is only used in one file so it should be static.

You might want to use the Fixes: commit ("")
tag? It will help people to pick the patch while
back-porting fixes to older kernels.'

For example:
https://lore.kernel.org/all/20230403072443.83810-2-d-gole@ti.com/

Fixes: 0651a730924b ("gpio: davinci: Add support for system 
suspend/resume PM")
