Merge tag 'asoc-v4.16-5' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound
Pull more ASoC updates from Mark Brown:
"With the merge window having been delayed for another week here's
another batch of updates that came in during that week.
There's a few important fixes in here, mainly a fix for I/O on a
number of devices caused by some of the component rework and a fix for
a potential issue if more than one component in a link provides
compressed operations. The I/O fixes are particularly important as the
problem causes a power regression on a number of OMAP platforms"
