Merge tag 'staging-5.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging / IIO driver updates from Greg KH: "Here is the big set of IIO and staging driver patches for 5.14-rc1. Loads of IIO driver updates and additions in here, the shortlog has the full details. For the staging side, we moved a few drivers out of staging, and deleted the kpc2000 drivers as the original developer asked us to because no one was working on them anymore. Also in here are loads of coding style cleanups due to different intern projects focusing on the staging tree to try to get experience doing kernel development. All of these have been in the linux-next tree for a while with no reported problems" * tag 'staging-5.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (744 commits) staging: hi6421-spmi-pmic: cleanup some macros staging: hi6421-spmi-pmic: change identation of a table staging: hi6421-spmi-pmic: change a return code staging: hi6421-spmi-pmic: better name IRQs staging: hi6421-spmi-pmic: use devm_request_threaded_irq() staging: hisilicon,hi6421-spmi-pmic.yaml: cleanup descriptions spmi: hisi-spmi-controller: move driver from staging phy: phy-hi3670-usb3: move driver from staging into phy staging: rtl8188eu: remove include/rtw_debug.h header staging: rtl8188eu: remove GlobalDebugLevel variable staging: rtl8188eu: remove DRIVER_PREFIX preprocessor definition staging: rtl8188eu: remove RT_TRACE macro staging: rtl8188eu: remove all RT_TRACE calls from hal/rtl8188eu_recv.c staging: rtl8188eu: remove all RT_TRACE calls from hal/hal_intf.c staging: rtl8188eu: remove all RT_TRACE calls from hal/rtl8188eu_xmit.c staging: rtl8188eu: remove all RT_TRACE calls from core/rtw_xmit.c staging: rtl8188eu: remove all RT_TRACE calls from core/rtw_pwrctrl.c staging: rtl8188eu: remove all RT_TRACE calls from core/rtw_recv.c staging: rtl8188eu: remove all RT_TRACE calls from core/rtw_ioctl_set.c staging: rtl8188eu: remove all RT_TRACE calls from core/rtw_ieee80211.c ...
