Merge tag 'staging-5.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging / iio updates from Greg KH: "Here is the big staging and iio set of patches for the 5.5-rc1 release. It's the usual huge collection of cleanup patches all over the drivers/staging/ area, along with a new staging driver, and a bunch of new IIO drivers as well. Full details are in the shortlog, but all of these have been in linux-next for a long time with no reported issues" * tag 'staging-5.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (548 commits) staging: vchiq: Have vchiq_dump_* functions return an error code staging: vchiq: Refactor indentation in vchiq_dump_* functions staging: fwserial: Fix Kconfig indentation (seven spaces) staging: vchiq_dump: Replace min with min_t staging: vchiq: Fix block comment format in vchiq_dump() staging: octeon: indent with tabs instead of spaces staging: comedi: usbduxfast: usbduxfast_ai_cmdtest rounding error staging: most: core: remove sysfs attr remove_link staging: vc04: Fix Kconfig indentation staging: pi433: Fix Kconfig indentation staging: nvec: Fix Kconfig indentation staging: most: Fix Kconfig indentation staging: fwserial: Fix Kconfig indentation staging: fbtft: Fix Kconfig indentation fbtft: Drop OF dependency fbtft: Make use of device property API fbtft: Drop useless #ifdef CONFIG_OF and dead code fbtft: Describe function parameters in kernel-doc fbtft: Make sure string is NULL terminated staging: rtl8723bs: remove set but not used variable 'change', 'pos' ...
