From aa9f8328fc51460e15da129caf622b6560fa8c99 Mon Sep 17 00:00:00 2001 From: James Bottomley Date: Tue, 7 May 2013 14:44:06 -0700 Subject: [SCSI] sas: unify the pointlessly separated enums sas_dev_type and sas_device_type These enums have been separate since the dawn of SAS, mainly because the latter is a procotol only enum and the former includes additional state for libsas. The dichotomy causes endless confusion about which one you should use where and leads to pointless warnings like this: drivers/scsi/mvsas/mv_sas.c: In function 'mvs_update_phyinfo': drivers/scsi/mvsas/mv_sas.c:1162:34: warning: comparison between 'enum sas_device_type' and 'enum sas_dev_type' [-Wenum-compare] Fix by eliminating one of them. The one kept is effectively the sas.h one, but call it sas_device_type and make sure the enums are all properly namespaced with the SAS_ prefix.
