From e9b7ba7954fa8df6e021ee4bef084ed10eba2c2b Mon Sep 17 00:00:00 2001 From: "Maciej S. Szmigiero" Date: Sun, 31 Jan 2016 22:56:59 +0100 Subject: [PATCH] mfd: as3711: Set regmap config reg counts properly Regmap config max_register field should contain number of device last register, however num_reg_defaults_raw field should be set to register count instead (usually one register more than max_register). as3711 driver had both of these fields set to the same value, fix this by introducing separate defines for max register number and total count of registers.
