Merge tag 'regmap-v4.1' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap
Pull regmap update from Mark Brown: "Just one patch for regmap this time around, a change from Steven Rostedt to prettify the way we're making the regmap internal header available to the trace events (it turns out that the trace subsystem doesn't actually need to be in trace/events)" * tag 'regmap-v4.1' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap: regmap: Move tracing header into drivers/base/regmap
