Merge tag 'staging-3.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging into next
Pull staging driver updates from Greg KH: "Here is the big staging driver pull request for 3.16-rc1. Lots of stuff here, tons of cleanup patches, a few new drivers, and some removed as well, but I think we are still adding a few thousand more lines than we remove, due to the new drivers being bigger than the ones deleted. One notible bit of work did stand out, Jes Sorensen has gone on a tear, fixing up a wireless driver to be "more sane" than it originally was from the vendor, with over 500 patches merged here. Good stuff, and a number of users laptops are better off for it. All of this has been in linux-next for a while" * tag 'staging-3.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (1703 commits) staging: skein: fix sparse warning for static declarations staging/mt29f_spinand: coding style fixes staging: silicom: fix sparse warning for static variable staging: lustre: Fix coding style staging: android: binder.c: Use more appropriate functions for euid retrieval staging: lustre: fix integer as NULL pointer warnings Revert "staging: dgap: remove unneeded kfree() in dgap_tty_register_ports()" Staging: rtl8192u: r8192U_wx.c Fixed a misplaced brace staging: ion: shrink highmem pages on kswapd staging: ion: use compound pages on high order pages for system heap staging: ion: remove struct ion_page_pool_item staging: ion: simplify ion_page_pool_total() staging: ion: tidy up a bit staging: rtl8723au: Remove redundant casting in usb_ops_linux.c staging: rtl8723au: Remove redundant casting in rtl8723a_hal_init.c staging: rtl8723au: Remove redundant casting in rtw_xmit.c staging: rtl8723au: Remove redundant casting in rtw_wlan_util.c staging: rtl8723au: Remove redundant casting in rtw_sta_mgt.c staging: rtl8723au: Remove redundant casting in rtw_recv.c staging: rtl8723au: Remove redundant casting in rtw_mlme.c ...
