[PATCH v4 0/5] libsas cleanups

[Damien Le Moal]

Martin, John,

While debugging an issue with the pm8001 driver, I generated these
cleanup patches. No functional changes overall.

These patches are against the 6.17/scsi-staging branch of the scsi tree.

Changes from v3:
 - Corrected commit message of patch 2
 - Added review tags

Changes from v2:
 - Modified patch 2 to remove the unnecessary check using dev_is_ata()
 - Added review tags

Changes from v1:
 - Added patch 1
 - Modified patch 2 to not inline sas_ata_wait_eh()
 - Added review tags

Damien Le Moal (5):
  scsi: libsas: Refactor dev_is_sata()
  scsi: libsas: Simplify sas_ata_wait_eh()
  scsi: libsas: Make sas_get_ata_info() static
  scsi: libsas: Move declarations of internal functions to sas_internal.h
  scsi: libsas: Use a bool for sas_deform_port() second argument

[PATCH v4 1/5] scsi: libsas: Refactor dev_is_sata()

[Damien Le Moal]

Use a switch statement in dev_is_sata() to make the code more readable
(and probably slightly better than a series of or conditions). Also have
this inline function return a boolean instead of an integer.

No functional changes.

[PATCH v4 2/5] scsi: libsas: Simplify sas_ata_wait_eh()

[Damien Le Moal]

Simplify the code of sas_ata_wait_eh(), removing the local variable ap
for the pointer to the device ata_port structure. The test using
dev_is_sata() is also removed as all call sites of this function check
if the device is a SATA one before calling this function.

[PATCH v4 3/5] scsi: libsas: Make sas_get_ata_info() static

[Damien Le Moal]

The function sas_get_ata_info() is used only in
drivers/scsi/libsas/sas_ata.c. Remove its definition from
include/scsi/sas_ata.h and make this function static.
