From 328f494d95aac8bd4896aea2328bc281053bcb71 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Sat, 7 Mar 2015 17:10:01 +0100 Subject: [PATCH] regmap: regcache-rbtree: Fix present bitmap resize When inserting a new register into a block at the lower end the present bitmap is currently shifted into the wrong direction. The effect of this is that the bitmap becomes corrupted and registers which are present might be reported as not present and vice versa. Fix this by shifting left rather than right.
