From d857d9a0adf49e332413d918322405192aafc766 Mon Sep 17 00:00:00 2001 From: Maciej Trela Date: Tue, 12 Apr 2011 17:28:39 -0700 Subject: [PATCH] isci: remove base_phy abstraction Merge struct sci_base_phy into scic_sds_phy. Until now sci_base_phy was referenced using scic_sds_phy->parent field. 'sci_base_phy' state machine handlers were also merged into scic_sds_phy state handlers.
