This first part of this series (patches 1 to 24) fixes handling of NCQ NON DATA commands in libsas and many bugs in the pm8001 driver. The fixes for the pm8001 driver include: * Suppression of all sparse warnings, fixing along the way many le32 handling bugs for big-endian architectures * Fix handling of NCQ NON DATA commands * Fix of tag values handling (0 *is* a valid tag value) * Fix many tag iand memory leaks in error path * Fix NCQ error recovery (abort all task execution) that was causing a crash The second part of the series (patches 24 to 31) add a small cleanup of libsas code and many simplifications and iomprovements of the pm8001 driver code. With these fixes, libzbc test suite passes all test case. This test suite was used with an SMR drive for testing because it generates many NCQ NON DATA commands (for zone management commands) and also generates many NCQ command errors to check ASC/ASCQ returned by the device. With the test suite, the error recovery path was extensively exercised. The same tests were also executed with a SAS SMR drives to exercise the error path. The patches are based on the latest 5.18/scsi-staging tree. Changes from v4: * Extracted code style changes in patch 22 into the new patch 24 * Squashed patch 18 into patch 22 (now patch 21) * Added reviewed-by tags Changes from v3: * Rebase on latest 5.18/scsi-staging tree * Dropped former patch 24 (kdoc comment fixed upstream already) * Merged former patch 27 and 30 * Fixed patch 26 commit message * Added patches 30 and 31 * Added reviewed-by tags Changes from v2: * Reorganized the series: fixes first, cleanups second. * Added more bug/leaks fix patches * Addressed Gary's comment for the ccb alloc helper (patch 28) * Rebased (and tested) all patches on 5.18/scsi-staging Changes from v1: * Added reviewed-by tags * Addressed Christoph's comments on patch 4 and 8 * Added patches 21 and 22 to fix 2 additional problems found while preparing this v2 series * Added patch 23 and 24 to cleanup the code further.
