Merge tag 'staging-3.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging drivers patches from Greg KH: "Here's the big staging driver tree update for 3.20-rc1. Lots of little things in here, adding up to lots of overall cleanups. The IIO driver updates are also in here as they cross the staging tree boundry a lot. I2O has moved into staging as well, as a plan to drop it from the tree eventually as that's a dead subsystem. All of this has been in linux-next with no reported issues for a while" * tag 'staging-3.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (740 commits) staging: lustre: lustre: libcfs: define symbols as static staging: rtl8712: Do coding style cleanup staging: lustre: make obd_updatemax_lock static staging: rtl8188eu: core: switch with redundant cases staging: rtl8188eu: odm: conditional setting with no effect staging: rtl8188eu: odm: condition with no effect staging: ft1000: fix braces warning staging: sm7xxfb: fix remaining CamelCase staging: sm7xxfb: fix CamelCase staging: rtl8723au: multiple condition with no effect - if identical to else staging: sm7xxfb: make smtc_scr_info static staging/lustre/mdc: Initialize req in mdc_enqueue for !it case staging/lustre/clio: Do not allow group locks with gid 0 staging/lustre/llite: don't add to page cache upon failure staging/lustre/llite: Add exception entry check after radix_tree staging/lustre/libcfs: protect kkuc_groups from write access staging/lustre/fld: refer to MDT0 for fld lookup in some cases staging/lustre/llite: Solve a race to access lli_has_smd in read case staging/lustre/ptlrpc: hold rq_lock when modify rq_flags staging/lustre/lnet: portal spreading rotor should be unsigned ...
