Revision e543c8a92fb6eca8dd554561fa55bba5f2a90d09 authored by Linus Torvalds on 05 June 2017, 22:31:14 UTC, committed by Linus Torvalds on 05 June 2017, 22:31:14 UTC
Pull libata fixes from Tejun Heo:

 - Revert of sata_mv devm_ioremap_resource() conversion. It made init
   fail if there are overlapping resources which led to detection
   failures on some setups.

 - A workaround for an Acer laptop which sometimes reports corrupt port
   map.

 - Other non-critical fixes.
