Merge tag 'char-misc-3.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc
Pull char/misc updates from Greg KH: "Here's the big char/misc driver tree merge for 3.11-rc1 A variety of different driver patches here. All of these have been in linux-next for a while, and the networking patches were acked-by David Miller, as it made sense for those patches to come through this tree" * tag 'char-misc-3.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (102 commits) Revert "char: misc: assign file->private_data in all cases" drivers: uio_pdrv_genirq: Use of_match_ptr() macro mei: check whether hw start has succeeded mei: check if the hardware reset succeeded mei: mei_cl_connect: don't multiply the timeout twice mei: do not override a client writing state when buffering mei: move mei_cl_irq_write_complete to client.c UIO: Fix concurrency issue drivers: uio_dmem_genirq: Use of_match_ptr() macro char: misc: assign file->private_data in all cases drivers: hv: allocate synic structures before hv_synic_init() drivers: hv: check interrupt mask before read_index vme: vme_tsi148.c: fix error return code in tsi148_probe() FMC: fix error handling in probe() function fmc: avoid readl/writel namespace conflict FMC: NULL dereference on allocation failure UIO: fix uio_pdrv_genirq with device tree but no interrupt UIO: allow binding uio_pdrv_genirq.c to devices using command line option FMC: add a char-device mezzanine driver FMC: add a driver to write mezzanine EEPROM ...
