We get 1 warning when building kernel with W=1: drivers/regulator/dbx500-prcmu.c:158:27: warning: no previous prototype for 'dbx500_regulator_testcase' [-Wmissing-prototypes]
In fact, this function is not declared in any file, but should be declared in a header file. thus can be recognized in other file. So this patch adds the declaration into drivers/regulator/dbx500-prcmu.h.
