Subject: regulator_lock_supply warning: unused variable 'i'


Hi Mark, Liam, and all

I always get this warning from regulator_lock_supply

	LINUX/drivers/regulator/core.c: In function 'regulator_lock_supply':
	LINUX/drivers/regulator/core.c:142:6: warning: unused variable 'i' [-Wunused-variable]
	  int i = 0;

my .config has

	> grep CONFIG_DEBUG_LOCK_ALLOC .config
	# CONFIG_DEBUG_LOCK_ALLOC is not set


I don't like this bad idea, but...

	#ifdef CONFIG_DEBUG_LOCK_ALLOC
		int i = 0;
	#endif
