Subject: scsi: hisi_sas: Change return variable type in phy_up_v3_hw()
Patch-mainline: v5.1-rc1
Git-commit: fba770c6682447f1998267f4143595e77be4f112
References: bsc#1140683

According to the tool fortify, phy_up_v3_hw() returns signed value, while
it should return an unsigned value.

So change variable "res" from int to irq_return_t.
