[PATCH v3 08/16] freezer: convert freezable helpers to static inline where possible

[Colin Cross <ccross@android.com>]

Some of the freezable helpers have to be macros because their
condition argument needs to get evaluated every time through
the wait loop.  Convert the others to static inline to make
future changes easier.
