Merge tag 'staging-4.12-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 tree update for 4.12-rc1. It's a big one, adding about 350k new lines of crap^Wcode, mostly all in a big dump of media drivers from Intel. But there's other new drivers in here as well, yet-another-wifi driver, new IIO drivers, and a new crypto accelerator. We also deleted a bunch of stuff, mostly in patch cleanups, but also the Android ION code has shrunk a lot, and the Android low memory killer driver was finally deleted, much to the celebration of the -mm developers. All of these have been in linux-next with a few build issues that will show up when you merge to your tree" Merge conflicts in the new rtl8723bs driver (due to the wifi changes this merge window) handled as per linux-next, courtesy of Stephen Rothwell. * tag 'staging-4.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (1182 commits) staging: fsl-mc/dpio: add cpu <--> LE conversion for dpaa2_fd staging: ks7010: remove line continuations in quoted strings staging: vt6656: use tabs instead of spaces staging: android: ion: Fix unnecessary initialization of static variable staging: media: atomisp: fix range checking on clk_num staging: media: atomisp: fix misspelled word in comment staging: media: atomisp: kmap() can't fail staging: atomisp: remove #ifdef for runtime PM functions staging: atomisp: satm include directory is gone atomisp: remove some more unused files atomisp: remove hmm_load/store/clear indirections atomisp: kill off mmgr_free atomisp: clean up the hmm init/cleanup indirections atomisp: handle allocation calls before init in the hmm layer staging: fsl-dpaa2/eth: Add maintainer for Ethernet driver staging: fsl-dpaa2/eth: Add TODO file staging: fsl-dpaa2/eth: Add trace points staging: fsl-dpaa2/eth: Add driver specific stats staging: fsl-dpaa2/eth: Add ethtool support staging: fsl-dpaa2/eth: Add Freescale DPAA2 Ethernet driver ...
