From fb44f3cec35c6e71865012fa281ba6d4ff50a99a Mon Sep 17 00:00:00 2001 From: Charles Keepax Date: Thu, 22 Feb 2018 12:59:14 +0000 Subject: regmap: Merge redundant handling in regmap_bulk_write The handling for the first two cases in regmap_bulk_write is essentially identical. The first case is just a better implementation of the second, supporting 8 byte registers and doing the locking manually to avoid bouncing the lock for each register. Drop some redundant code by removing the second of these cases and allowing both situations to be handled by the same code.
