Merge tag 'staging-3.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging tree patches from Greg Kroah-Hartman: "Here's the big staging tree merge for the 3.6-rc1 merge window. There are some patches in here outside of drivers/staging/, notibly the iio code (which is still stradeling the staging / not staging boundry), the pstore code, and the tracing code. All of these have gotten acks from the various subsystem maintainers to be included in this tree. The pstore and tracing patches are related, and are coming here as they replace one of the android staging drivers. Otherwise, the normal staging mess. Lots of cleanups and a few new drivers (some iio drivers, and the large csr wireless driver abomination.) Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>" Fixed up trivial conflicts in drivers/staging/comedi/drivers/s626.h and drivers/staging/gdm72xx/netlink_k.c * tag 'staging-3.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (1108 commits) staging: csr: delete a bunch of unused library functions staging: csr: remove csr_utf16.c staging: csr: remove csr_pmem.h staging: csr: remove CsrPmemAlloc staging: csr: remove CsrPmemFree() staging: csr: remove CsrMemAllocDma() staging: csr: remove CsrMemCalloc() staging: csr: remove CsrMemAlloc() staging: csr: remove CsrMemFree() and CsrMemFreeDma() staging: csr: remove csr_util.h staging: csr: remove CsrOffSetOf() stating: csr: remove unneeded #includes in csr_util.c staging: csr: make CsrUInt16ToHex static staging: csr: remove CsrMemCpy() staging: csr: remove CsrStrLen() staging: csr: remove CsrVsnprintf() staging: csr: remove CsrStrDup staging: csr: remove CsrStrChr() staging: csr: remove CsrStrNCmp staging: csr: remove CsrStrCmp ...
