Merge tag 'staging-4.20-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging and IIO driver fixes from Greg KH: "Here are some small IIO and staging driver fixes for 4.20-rc5. Nothing major, the IIO fix ended up touching the HID drivers at the same time, but the HID maintainer acked it. The staging fixes are all minor patches for reported issues and regressions, full details are in the shortlog. All of these have been in linux-next for a while with no reported issues" * tag 'staging-4.20-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: iio/hid-sensors: Fix IIO_CHAN_INFO_RAW returning wrong values for signed numbers staging: vchiq_arm: fix compat VCHIQ_IOC_AWAIT_COMPLETION staging: mt7621-pinctrl: fix uninitialized variable ngroups staging: rtl8723bs: Add missing return for cfg80211_rtw_get_station staging: most: use format specifier "%s" in snprintf staging: rtl8723bs: Fix incorrect sense of ether_addr_equal staging: mt7621-dma: fix potentially dereferencing uninitialized 'tx_desc' staging: comedi: clarify/unify macros for NI macro-defined terminals drivers: staging: cedrus: find ctx before dereferencing it ctx staging: rtl8723bs: Fix the return value in case of error in 'rtw_wx_read32()' staging: comedi: ni_mio_common: scale ao INSN_CONFIG_GET_CMD_TIMING_CONSTRAINTS iio:st_magn: Fix enable device after trigger
