[PATCH] regulator: 88pm8607: Fix off-by-one value range checkingin the case of no id is matched

From: Axel Lin
Date: Thu Aug 04 2011 - 04:18:28 EST


In the case of no id is matched, the variable i is equal to
ARRAY_SIZE(pm8607_regulator_info).

I think compare variable i with ARRAY_SIZE(pm8607_regulator_info) here is slightly
better in readability than compare with PM8607_ID_RG_MAX.
