Merge tag 'devfreq-next-for-5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/chanwoo/linux

Pull devfreq updates for v5.8 from Chanwoo Choi:

"1. Update devfreq core
 - Use lockdep function for checking mutex state instead of manual checking.
 - Replace strncpy with strscpy to fix the compile warning.

 2. Update devfreq driver
 - Add new imx-bus.c devfreq driver for controlling the bus frequenncy
   and it registers the imx interconnect device which indicates the imx-bus.c
   as the parent device. This relation make the connection between imx-bus.c
   and imx interconnect nodes. In result, the imx-bus.c devfreq driver handles
   the DEV_PM_QOS_MIN_FREQUENCY requirements from imx interconnect nodes
   in order to support the minimum bus bandwidth of interconnect nodes.

 - Delete unneed error message and update the boosting on tegra30-devfreq.c."
