[PATCH] regulator: raa215300: Change the scope of the variables {clkin_name, xin_name}

[Biju Das <biju.das.jz@xxxxxxxxxxxxxx>]

Change the scope of the variables {clkin_name, xin_name} from global->local
to fix the below warning.

drivers/regulator/raa215300.c:42:12: sparse: sparse: symbol 'xin_name' was
not declared. Should it be static?
