Merge tag 'mfd-fixes-4.7' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/mfd
Pull MFD fixes from Lee Jones:
"Contained are some standard fixes and unusually an extension to the
Reset API. Some of those changes are required to fix a bug introduced
in -rc1, which introduces extra 'reset line checks' i.e. whether the
line is shared or not. If a line is shared and the new *_shared() API
is not used, the request fails with an error. This breaks USB in v4.7
for ST's platforms.
Admittedly, there are some patches contained in our (MFD/Reset)
immutable branch which are not true -fixes, but there isn't anything I
can do about that. Rest assured though, there aren't any API
'changes'. Everything is the same from the consumer's perspective.
- Use new reset_*_get_shared() variant to prevent reset line
obtainment failure (Fixes commit 0b52297f2288: "reset: Add support
for shared reset controls")
- Fix unintentional switch() fall-through into error path
- Fix uninitialised variable compiler warning"
