From 0dc36888d4422140f9eaf50f24953ec109f750a3 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Tue, 18 Dec 2007 16:34:43 -0500 Subject: [PATCH] libata: rename ATA_PROT_ATAPI_* to ATAPI_PROT_* ATA_PROT_ATAPI_* are ugly and naming schemes between ATA_PROT_* and ATA_PROT_ATAPI_* are inconsistent causing confusion. Rename them to ATAPI_PROT_* and make them consistent with ATA counterpart.
