Merge tag 'staging-3.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging driver tree update from Greg Kroah-Hartman: "Here's the big staging driver tree update for 3.10-rc1 This update contains loads of comedi driver cleanups and fixes in here, iio updates, android driver changes, and other various staging driver cleanups. Thanks to some drivers being removed, and the comedi driver cleanups, we have removed more code than we added: 627 files changed, 65145 insertions(+), 76321 deletions(-) which is always nice to see. All of these have been in linux-next for a while." * tag 'staging-3.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (940 commits) staging: comedi: ni_labpc: fix legacy driver build staging: comedi: das800: cleanup the cio-das802/16 fifo comments staging: comedi: das800: rename CamelCase vars in das800_ai_do_cmd() staging: comedi: das800: tidy up the private data staging: comedi: das800: tidy up das800_interrupt() staging: comedi: das800: tidy up das800_ai_insn_read() staging: comedi: das800: tidy up das800_di_insn_bits() staging: comedi: das800: tidy up das800_do_insn_bits() staging: comedi: das800: remove extra divisor calculation call staging: comedi: das800: rename {enable,disable}_das800 staging: comedi: das800: tidy up subdevice init staging: comedi: das800: allow attaching without interrupt support staging: comedi: das800: interrupts are required for async command support staging: comedi: das800: tidy up das800_ai_do_cmdtest() staging: comedi: das800: remove 'volatile' on private data variables staging: comedi: das800: cleanup the boardinfo staging: comedi: das800: cleanup range table declarations staging: comedi: das800: introduce das800_ind_{write, read}() staging: comedi: das800: remove forward declarations staging: comedi: das800: move das800_set_frequency() ...
