Merge tag 'staging-4.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging/IIO updates from Greg KH: "Here's the "big" staging/iio pull request for 4.10-rc1. Not as big as 4.9 was, but still just over a thousand changes. We almost broke even of lines added vs. removed, as the slicoss driver was removed (got a "clean" driver for the same hardware through the netdev tree), and some iio drivers were also dropped, but I think we ended up adding a few thousand lines to the source tree in the end. Other than that it's a lot of minor fixes all over the place, nothing major stands out at all. All of these have been in linux-next for a while. There will be a merge conflict with Al's vfs tree in the lustre code, but the resolution for that should be pretty simple, that too has been in linux-next" * tag 'staging-4.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (1002 commits) staging: comedi: comedidev.h: Document usage of 'detach' handler staging: fsl-mc: remove unnecessary info prints from bus driver staging: fsl-mc: add sysfs ABI doc staging/lustre/o2iblnd: Fix misspelled attemps->attempts staging/lustre/o2iblnd: Fix misspelling intialized->intialized staging/lustre: Convert all bare unsigned to unsigned int staging/lustre/socklnd: Fix whitespace problem staging/lustre/o2iblnd: Add missing space staging/lustre/lnetselftest: Fix potential integer overflow staging: greybus: audio_module: remove redundant OOM message staging: dgnc: Fix lines longer than 80 characters staging: dgnc: fix blank line after '{' warnings. staging/android: remove Sync Framework tasks from TODO staging/lustre/osc: Revert erroneous list_for_each_entry_safe use staging: slicoss: remove the staging driver staging: lustre: libcfs: remove lnet upcall code staging: lustre: remove set but unused variables staging: lustre: osc: set lock data for readahead lock staging: lustre: import: don't reconnect during connect interpret staging: lustre: clio: remove mtime check in vvp_io_fault_start() ...
