Merge branch 'mips-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux
Pull MIPS fixes from Paul Burton: "Here are a few MIPS fixes, and a MAINTAINERS update to hand over MIPS maintenance to Thomas Bogendoerfer - this will be my final pull request as MIPS maintainer. Thanks for your helpful comments, useful corrections & responsiveness during the time I've fulfilled the role, and I'm sure I'll pop up elsewhere in the tree somewhere down the line" * 'mips-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/mips/linux: MAINTAINERS: Hand MIPS over to Thomas MIPS: ingenic: DTS: Fix watchdog nodes MIPS: X1000: Fix clock of watchdog node. MIPS: vdso: Wrap -mexplicit-relocs in cc-option MIPS: VPE: Fix a double free and a memory leak in 'release_vpe()' MIPS: cavium_octeon: Fix syncw generation. mips: vdso: add build time check that no 'jalr t9' calls left MIPS: Disable VDSO time functionality on microMIPS mips: vdso: fix 'jalr t9' crash in vdso code
