Merge tag 'docs-4.10-rc1-fix' of git://git.lwn.net/linux
Pull documentation fixes from Jonathan Corbet: "Two small fixes: - A merge error on my part broke the DocBook build. I've requisitioned one of tglx's frozen sharks for appropriate disciplinary action and resolved to be more careful about testing the DocBook stuff as long as it's still around. - Fix an error in unaligned-memory-access.txt" * tag 'docs-4.10-rc1-fix' of git://git.lwn.net/linux: Documentation/unaligned-memory-access.txt: fix incorrect comparison operator docs: Fix build failure
