That would be better if it's not too much trouble. A patch with a title
of "Make some functions static" shouldn't really be deleting functions
entirely.

In commit cb9e4d10c448 ("[POWERPC] Add support for 750CL Holly board")
new functions were added. Since these functions can be made static,
make it so. While doing so, it turns out that holly_power_off and
holly_halt are unused, so remove them.


I would have said 'since these functions are only used in this C file, 
make them static'.


I think this could be split in two patches:
1/ Remove unused functions, ie holly_halt() and holly_power_off().
2/ Make the other ones static.

[PATCH] powerpc: Make some functions static

2019-03-12 Thread Mathieu Malaterre
In commit cb9e4d10c448 ("[POWERPC] Add support for 750CL Holly board")
new functions were added. Since these functions can be made static,
make it so. While doing so, it turns out that holly_power_off and
holly_halt are unused, so remove them.
