| |
If function callers and providers do not share the same prototypes the compiler complains of missing prototypes. Fix this by moving the already existing prototypes out to a mutually convenient location.
Fixes the following W=1 kernel build warning(s):
drivers/cpufreq/pasemi-cpufreq.c:109:5: warning: no previous prototype for ‘check_astate’ [-Wmissing-prototypes] 109 | int check_astate(void) | ^~~~~~~~~~~~ drivers/cpufreq/pasemi-cpufreq.c:114:6: warning: no previous prototype for ‘restore_astate’ [-Wmissing-prototypes] 114 | void restore_astate(int cpu) | ^~~~~~~~~~~~~~
