From e08abeca39673e1045ca1e5a90bd7fef69d0fe8f Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Wed, 27 Feb 2019 09:30:53 +0800 Subject: regulator: wm8400: Get rid of wm8400_block_read/wm8400_set_bits functions The only user of wm8400_block_read/wm8400_set_bits functions is the wm8400 regulator driver. At the context of all the callers, we can use regmap_bulk_read/regmap_update_bits directly. Thus remove wm8400_block_read/wm8400_set_bits functions.
