Hi Niklas,
->port_start is NULL now but ata_sas_port_init() is still using it
without checking whether it is NULL. I know the patch #3 will remove it
finally. But this will bring a great inconvenience because the kernel
will crash when bisectting to this commit.
Either put patch #3 before this patch or fold patch #3 directly into
path #2 ?
Thanks,
Jason
