From: Maciej Trela Date: Wed, 13 Apr 2011 00:28:35 +0000 (-0700) Subject: isci: remove base_remote_device abstraction X-Git-Tag: v3.0-rc6~1^2~1^2~173 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=0ea99d52cbcdb4bf5f5dd3097088a2919a115981;p=karo-tx-linux.git isci: remove base_remote_device abstraction Merge struct sci_base_remote_device into scic_sds_remote_device. As for now sci_base_remote_device was accessed indirectly using scic_sds_remote_device->parent field. Both machine state handlers are also merged together.
