Merge tag 'staging-4.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging driver updates from Greg KH: "Here is the big staging driver pull request for 4.6-rc1. Lots of little things here, over 1600 patches or so. Notable is all of the good Lustre work happening, those developers have finally woken up and are cleaning up their code greatly. The Outreachy intern application process is also happening, which brought in another 400 or so patches. Full details are in the very long shortlog. All of these have been in linux-next with no reported issues" * tag 'staging-4.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (1673 commits) staging: lustre: fix aligments in lnet selftest staging: lustre: report minimum of two buffers for LNet selftest load test staging: lustre: test for proper errno code in lstcon_rpc_trans_abort staging: lustre: filter remaining extra spacing for lnet selftest staging: lustre: remove extra spacing when setting variable for lnet selftest staging: lustre: remove extra spacing of variable declartions for lnet selftest staging: lustre: fix spacing issues checkpatch reported in lnet selftest staging: lustre: remove returns in void function for lnet selftest staging: lustre: fix bogus lst errors for lnet selftest staging: netlogic: Replacing pr_err with dev_err after the call to devm_kzalloc staging: mt29f_spinand: Replacing pr_info with dev_info after the call to devm_kzalloc staging: android: ion: fix up file mode staging: ion: debugfs invalid gfp mask staging: rts5208: Replace pci_enable_device with pcim_enable_device Staging: ieee80211: Place constant on right side of the test. staging: speakup: Replace del_timer with del_timer_sync staging: lowmemorykiller: fix 2 checks that checkpatch complained staging: mt29f_spinand: Drop void pointer cast staging: rdma: hfi1: file_ops: Replace ALIGN with PAGE_ALIGN staging: rdma: hfi1: driver: Replace IS_ALIGNED with PAGE_ALIGNED ...
