From 5c1488906f852473b4d7837c3e33e411e0eb6910 Mon Sep 17 00:00:00 2001 From: "Maciej S. Szmigiero" Date: Sun, 31 Jan 2016 23:00:06 +0100 Subject: [PATCH] mfd: tps65090: 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). tps65090 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.
