Lennert, thanks a lot for sending this follow up patch.

However, checkpatch.pl complains:

ERROR: Please use git commit description style 'commit <12+ chars of sha1> ("<title line>")' - ie: 'commit 20730e9b2778 ("ahci: add 43-bit DMA address quirk for ASMedia ASM1061 controllers")'
#44: 
commit 20730e9b2778 to the other supported ASM106x parts as well.

Perhaps send a v2 with this fixed,
and Cc: stable like Damien requested.


Kind regards,
Niklas
