Merge tag 'staging-4.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging and IIO updates from Greg KH: "Here is the "big" staging and IIO driver update for 4.15-rc1. Lots and lots of little changes, almost all minor code cleanups as the Outreachy application process happened during this development cycle. Also happened was a lot of IIO driver activity, and the typec USB code moving out of staging to drivers/usb (same commits are in the USB tree on a persistent branch to not cause merge issues.) Overall, it's a wash, I think we added a few hundred more lines than removed, but really only a few thousand were modified at all. All of these have been in linux-next for a while. There might be a merge issue with Al's vfs tree in the pi433 driver (take his changes, they are always better), and the media tree with some of the odd atomisp cleanups (take the media tree's version)" * tag 'staging-4.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (507 commits) staging: lustre: add SPDX identifiers to all lustre files staging: greybus: Remove redundant license text staging: greybus: add SPDX identifiers to all greybus driver files staging: ccree: simplify ioread/iowrite staging: ccree: simplify registers access staging: ccree: simplify error handling logic staging: ccree: remove dead code staging: ccree: handle limiting of DMA masks staging: ccree: copy IV to DMAable memory staging: fbtft: remove redundant initialization of buf staging: sm750fb: Fix parameter mistake in poke32 staging: wilc1000: Fix bssid buffer offset in Txq staging: fbtft: fb_ssd1331: fix mirrored display staging: android: Fix checkpatch.pl error staging: greybus: loopback: convert loopback to use generic async operations staging: greybus: operation: add private data with get/set accessors staging: greybus: loopback: Fix iteration count on async path staging: greybus: loopback: Hold per-connection mutex across operations staging: greybus/loopback: use ktime_get() for time intervals staging: fsl-dpaa2/eth: Extra headroom in RX buffers ...
