Merge tag 'char-misc-4.15-rc1' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc
Pull char/misc updates from Greg KH: "Here is the big set of char/misc and other driver subsystem patches for 4.15-rc1. There are small changes all over here, hyperv driver updates, pcmcia driver updates, w1 driver updats, vme driver updates, nvmem driver updates, and lots of other little one-off driver updates as well. The shortlog has the full details. All of these have been in linux-next for quite a while with no reported issues" * tag 'char-misc-4.15-rc1' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (90 commits) VME: Return -EBUSY when DMA list in use w1: keep balance of mutex locks and refcnts MAINTAINERS: Update VME subsystem tree. nvmem: sunxi-sid: add support for A64/H5's SID controller nvmem: imx-ocotp: Update module description nvmem: imx-ocotp: Enable i.MX7D OTP write support nvmem: imx-ocotp: Add i.MX7D timing write clock setup support nvmem: imx-ocotp: Move i.MX6 write clock setup to dedicated function nvmem: imx-ocotp: Add support for banked OTP addressing nvmem: imx-ocotp: Pass parameters via a struct nvmem: imx-ocotp: Restrict OTP write to IMX6 processors nvmem: uniphier: add UniPhier eFuse driver dt-bindings: nvmem: add description for UniPhier eFuse nvmem: set nvmem->owner to nvmem->dev->driver->owner if unset nvmem: qfprom: fix different address space warnings of sparse nvmem: mtk-efuse: fix different address space warnings of sparse nvmem: mtk-efuse: use stack for nvmem_config instead of malloc'ing it nvmem: imx-iim: use stack for nvmem_config instead of malloc'ing it thunderbolt: tb: fix use after free in tb_activate_pcie_devices MAINTAINERS: Add git tree for Thunderbolt development ...
