Merge tag 'char-misc-3.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc
Pull char/misc patches from Greg KH: "Here's the big char/misc driver patchset for 3.13-rc1. Lots of stuff in here, including some new drivers for Intel's "MIC" co-processor devices, and a new eeprom driver. Other things include the driver attribute cleanups, extcon driver updates, hyperv updates, and a raft of other miscellaneous driver fixes. All of these have been in linux-next for a while" * tag 'char-misc-3.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (121 commits) misc: mic: Fixes for randconfig build errors and warnings. tifm: fix error return code in tifm_7xx1_probe() w1-gpio: Use devm_* functions w1-gpio: Detect of_gpio_error for first gpio uio: Pass pointers to virt_to_page(), not integers uio: fix memory leak misc/at24: avoid infinite loop on write() misc/93xx46: avoid infinite loop on write() misc: atmel_pwm: add deferred-probing support mei: wd: host_init propagate error codes from called functions mei: replace stray pr_debug with dev_dbg mei: bus: propagate error code returned by mei_me_cl_by_id mei: mei_cl_link remove duplicated check for open_handle_count mei: print correct device state during unexpected reset mei: nfc: fix memory leak in error path lkdtm: add tests for additional page permissions lkdtm: adjust recursion size to avoid warnings lkdtm: isolate stack corruption test mei: move host_clients_map cleanup to device init mei: me: downgrade two errors to debug level ...
