Merge remote-tracking branch 'regmap/fix/rbtree' into regmap-linus

regmap: Fixes for v4.8
Several fixes here, the main one being the change from Lars-Peter which
I'd been letting soak in -next since the merge window in case it
uncovered further issues as it's a minimal fix rather than a change
addressing the root cause of the problems (which would've been too
invasive for -rc):
- The biggest change is a fix from Lars-Peter to ensure that we don't
create overlapping rbtree nodes which in turn avoids returning
corrupt cache values to users, fixing some issues that were exposed
by some recent optimisations with certain access patterns but had
been present for a long time.
- A fix from Elaine Zhang to stop us updating the cache if we get an
I/O error when writing to the hardware.
- A fix fromm Maarten ter Huurne to avoid uninitialized defaults in
cases where we have non-readable registers but are initializing the
cache by reading from the device.
