Subject: PM / OPP: rename header to linux/pm_opp.h
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e4db1c7439b31993a4886b273bb9235a8eea82bf;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

PM / OPP: rename header to linux/pm_opp.h

Since Operating Performance Points (OPP) functions are specific
to device specific power management, be specific and rename opp.h
to pm_opp.h
