Merge tag 'staging-3.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging tree merge from Greg KH: "Here's the bit staging tree pull request for 3.12-rc1. Lots of staging driver updates, and fixes. Lustre is finally enabled in the build, and lots of cleanup started happening in it. There's a new wireless driver in here, and 2 new TTY drivers, which cause the overall lines added/removed to be quite large on the "added" side. The IIO driver updates are also coming through here, as they are tied to the staging iio drivers" * tag 'staging-3.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (942 commits) staging: dwc2: make dwc2_core_params documentation more complete staging: dwc2: validate the value for phy_utmi_width staging: dwc2: interpret all hwcfg and related register at init time staging: dwc2: properly mask the GRXFSIZ register staging: dwc2: remove redundant register reads staging: dwc2: re-use hptxfsiz variable staging: dwc2: simplify debug output in dwc_hc_init staging: dwc2: add missing shift staging: dwc2: simplify register shift expressions staging: dwc2: only read the snpsid register once staging: dwc2: unshift non-bool register value constants staging: dwc2: fix off-by-one in check for max_packet_count parameter staging: dwc2: remove specific fifo size constants Staging:BCM:DDRInit.c:Renaming __FUNCTION__ staging: bcm: remove Version.h file. staging: rtl8188eu: off by one in rtw_set_802_11_add_wep() staging: r8188eu: copying one byte too much staging: rtl8188eu: || vs && typo staging: r8188eu: off by one bugs staging: crystalhd: Resolve sparse 'different base types' warnings. ...
