Subject: [PATCH] regulator: pfuze100: Fix off-by-one for max_register setting
Date: Thu, 01 Aug 2013 19:59:56 +0800	[thread overview]
Message-ID: <1375358396.15804.1.camel@phoenix> (raw)

max_register should be register count - 1.

Hi Robin,
I don't have the datasheet, can you check if this patch is correct or not?
If PFUZE_NUMREGS really means register count, I think this fix is required.

Thanks,
Axel
