Merge tag 'for-5.14/libata-2021-06-27' of git://git.kernel.dk/linux-block
Pull libata updates from Jens Axboe:
"The big change in this round is that we're finally in a position where
we can sanely remove the old drivers/ide/ code, as libata covers
everything we need by now.
This is exciting for two reasons:
1) we delete a lot of legacy code that doesn't really meet the
standards we have today, and
2) it enables us to clean up various bits in the block layer that
exist only because of the old IDE code.
Outside of that, just a few minor fixes here, fixups for warnings,
etc"
