Merge tag 'char-misc-3.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc
Pull Char/Misc driver merge from Greg Kroah-Hartman: "Here is the "big" char/misc driver patches for 3.8-rc1. I'm starting to put random driver subsystems that I had previously sent you through the driver-core tree in this tree, as it makes more sense to do so. Nothing major here, the various __dev* removals, some mei driver updates, and other random driver-specific things from the different maintainers and developers. Note, some MFD drivers got added through this tree, and they are also coming in through the "real" MFD tree as well, due to some major mis-communication between me and the different developers. If you have any merge conflicts, take the ones from the MFD tree, not these ones, sorry about that. All of this has been in linux-next for a while. Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>" Fix up trivial conflict in drivers/mmc/host/Kconfig due to new drivers having been added (both at the end, as usual..) * tag 'char-misc-3.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (84 commits) MAINTAINERS: remove drivers/staging/hv/ misc/st_kim: Free resources in the error path of probe() drivers/char: for hpet, add count checking, and ~0UL instead of -1 w1-gpio: Simplify & get rid of defines w1-gpio: Pinctrl-fy extcon: remove use of __devexit_p extcon: remove use of __devinit extcon: remove use of __devexit drivers: uio: Only allocate new private data when probing device tree node drivers: uio_dmem_genirq: Allow partial success when opening device drivers: uio_dmem_genirq: Don't use DMA_ERROR_CODE to indicate unmapped regions drivers: uio_dmem_genirq: Don't mix address spaces for dynamic region vaddr uio: remove use of __devexit uio: remove use of __devinitdata uio: remove use of __devinit uio: remove use of __devexit_p char: remove use of __devexit char: remove use of __devinitconst char: remove use of __devinitdata char: remove use of __devinit ...
