[PATCH RESEND 1/2] regulator: aat2870: Fix the logic of checking if no id is matched in aat2870_get_regulator

[Axel Lin <axel.lin@gmail.com>]

In current implementation, the pointer ri is not NULL if no id is matched.
Fix it by checking i == ARRAY_SIZE(aat2870_regulators) if no id is matched.

It was sent on https://lkml.org/lkml/2011/7/5/559
and resent on https://lkml.org/lkml/2011/8/31/122.

Seems this patch is lost so I resend it again.
