Merge branch 'for-4.13-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata
Pull libata fixes from Tejun Heo:
"Late fixes for libata. There's a minor platform driver fix but the
important one is READ LOG PAGE.
This is a new ATA command which is used to test some optional features
but it broke probing of some devices - they locked up instead of
failing the unknown command.
Christoph tried blacklisting, but, after finding out there are
multiple devices which fail this way, backed off to testing feature
bit in IDENTIFY data first, which is a bit lossy (we can miss features
on some devices) but should be a lot safer"
* 'for-4.13-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata:
Revert "libata: quirk read log on no-name M.2 SSD"
libata: check for trusted computing in IDENTIFY DEVICE data
libata: quirk read log on no-name M.2 SSD
sata: ahci-da850: Fix some error handling paths in 'ahci_da850_probe()'
