[PATCH v3 0/8] scsi: libsas: sas address comparation refactor

From: Jason Yan
Date: Mon Sep 26 2022 - 22:19:12 EST


Sas address conversion and comparation is widely used in libsas and
drivers. However they are all opencoded and to avoid the line spill over
80 columns, are mostly split into multi-lines.

To make the code easier to read, introduce some helpers with clearer
semantics and replace the opencoded segments with them.

v2->v3:
Rename sas_phy_addr_same() to sas_phy_addr_match().
Rearrange patches, move patch #6 to #1 and directly use the helper
sas_phy_match_dev_addr() in sas_find_attached_phy().
Add some review tags from Jack Wang.

v1->v2:
First factor out sas_find_attached_phy() and replace LLDDs's code
with it.
Remove three too simple helpers.
Rename the helpers with 'sas_' prefix.
