Hello Mikko,
I tried to apply this commit, but it fails with:
Applying: ata: libata: disable LPM for WDC WD20EFAX-68FB5N0 hard drives
Patch failed at 0001 ata: libata: disable LPM for WDC WD20EFAX-68FB5N0 hard drives
error: corrupt patch at line 10
Please use:
$ git format-patch -1
You should then get a foo.patch.
You should then be able to do (locally):
$ git checkout HEAD~
$ git am foo.patch
to verify that the commit can be applied.
Kind regards,
Niklas
