Merge tag 'regmap-fix-v4.0-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap
Pull regmap fix from Mark Brown:
"This patch fixes a bad interaction between the support that was added
for having regmaps without devices for early system controller
initialization and the trace support.
There's a very good analysis of the actual issue in the commit message
for the change"
* tag 'regmap-fix-v4.0-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap:
regmap: introduce regmap_name to fix syscon regmap trace events
