From 5cb0789de1fe3b8be2d0ab9a78451a48ae07e74c Mon Sep 17 00:00:00 2001 From: Charles Keepax Date: Tue, 24 Apr 2018 16:05:51 +0100 Subject: [PATCH] iio: accel: bcm150: Remove handling for regmap raw_read_max The regmap core now handles splitting up transactions according to max_raw_read, so this code is no longer required in client drivers.
