Nothing major here, just some small bugfixes found by people testing, and a MAINTAINERS file update for the genwqe driver. All have been in linux-next with no reported issues" [ The cxl driver fix came in through the powerpc tree earlier ] * tag 'char-misc-4.12-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: cxl: Avoid double free_irq() for psl,slice interrupts mei: make sysfs modalias format similar as uevent modalias drivers: char: mem: Fix wraparound check to allow mappings up to the end MAINTAINERS: Change maintainer of genwqe driver goldfish_pipe: use GFP_ATOMIC under spin lock firmware: vpd: do not leak kobjects firmware: vpd: avoid potential use-after-free when destroying section firmware: vpd: do not leave freed section attributes to the list
