Merge tag 'sound-4.13-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound into asoc-rt5677
sound fixes for 4.13-rc7 We're keeping in a good shape, this batch contains just a few small fixes (a regression fix for ASoC rt5677 codec, NULL dereference and error-path fixes in firewire, and a corner-case ioctl error fix for user TLV), as well as usual quirks for USB-audio and HD-audio.
