Patch 9f01cd4a91 (regulator: core: introduce function to lock
regulators and its supplies) introduces function
regulator_lock_supply(). On my kernel it causes compile-time
error:
drivers/regulator/core.c: In function ‘regulator_lock_supply’:
drivers/regulator/core.c:142:6: warning: unused variable ‘i’ [-Wunused-variable]
int i = 0;
Please pull this fix.
