Pull staging / IIO driver updates from Greg KH: "Here is the big staging and IIO driver pull request for 5.11-rc1 Lots of different things in here: - loads of driver updates - so many coding style cleanups - new IIO drivers - Android ION code is finally removed from the tree - wimax drivers are moved to staging on their way out of the kernel Nothing really exciting, just the constant grind of kernel development :) All have been in linux-next for a while with no reported issues" * tag 'staging-5.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (341 commits) staging: olpc_dcon: Do not call platform_device_unregister() in dcon_probe() staging: most: Fix spelling mistake "tranceiver" -> "transceiver" staging: qlge: remove duplicate word in comment staging: comedi: mf6x4: Fix AI end-of-conversion detection staging: greybus: Add TODO item about modernizing the pwm code pinctrl: ralink: add a pinctrl driver for the rt2880 family dt-bindings: pinctrl: rt2880: add binding document staging: rtl8723bs: remove ELEMENT_ID enum staging: rtl8723bs: remove unused macros staging: rtl8723bs: replace EID_EXTCapability staging: rtl8723bs: replace EID_BSSIntolerantChlReport staging: rtl8723bs: replace EID_BSSCoexistence staging: rtl8723bs: replace _MME_IE_ staging: rtl8723bs: replace _WAPI_IE_ staging: rtl8723bs: replace _EXT_SUPPORTEDRATES_IE_ staging: rtl8723bs: replace _ERPINFO_IE_ staging: rtl8723bs: replace _CHLGETXT_IE_ staging: rtl8723bs: replace _COUNTRY_IE_ staging: rtl8723bs: replace _IBSS_PARA_IE_ staging: rtl8723bs: replace _TIM_IE_ ...
