Merge tag 'staging-4.7-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull IIO and staging fixes from Greg KH: "Here are a number of IIO and staging bugfixes for 4.7-rc4. Nothing huge, the normal amount of iio driver fixes, and some small staging driver bugfixes for some reported problems (2 are reverts of patches that went into 4.7-rc1). All have been in linux-next with no reported issues" * tag 'staging-4.7-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (24 commits) Revert "Staging: rtl8188eu: rtw_efuse: Use sizeof type *pointer instead of sizeof type." Revert "Staging: drivers: rtl8188eu: use sizeof(*ptr) instead of sizeof(struct)" staging: lustre: lnet: Don't access NULL NI on failure path iio: hudmidity: hdc100x: fix incorrect shifting and scaling iio: light apds9960: Add the missing dev.parent iio: Fix error handling in iio_trigger_attach_poll_func iio: st_sensors: Disable DRDY at init time iio: st_sensors: Init trigger before irq request iio: st_sensors: switch to a threaded interrupt iio: light: bh1780: assign a static name iio: bh1780: dereference the client properly iio: humidity: hdc100x: fix IIO_TEMP channel reporting iio:st_pressure: fix sampling gains (bring inline with ABI) iio: proximity: as3935: fix buffer stack trashing iio: proximity: as3935: remove triggered buffer processing iio: proximity: as3935: correct IIO_CHAN_INFO_RAW output max44000: Remove scale from proximity iio: humidity: am2315: Remove a stray unlock iio: humidity: hdc100x: correct humidity integration time mask iio: pressure: bmp280: fix error message for wrong chip id ...
