Return the error code when sas_find_attached_phy_id() failed.

This 'Fixes' tag is not right. This commit is only a refactor and did
not change the original logic here.
Hi, Jason
Thanks for your reply. But I think the logic of this code is changed.
I,m talking about the Fixes tag: ec64858657a8 ("scsi: pm8001: Use
sas_find_attached_phy_id() instead of open coding it"
That commit did not change the original logic. So your patch is not
fixing that commit.

Before this patch, we won't go to label 'found_out', and will call
PM8001_CHIP_DISP->reg_dev_req() ....
After this patch, we just free the 'pm8001_device' and return the error
code.
Or maybe I misunderstand somewhere?
Sorry, but I'm not talking about your patch.
Thanks,
