From: Maciej Patelczyk Date: Thu, 28 Apr 2011 22:06:21 +0000 (+0000) Subject: isci: Removed sci_base_object from scic_sds_remote_device. X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=5d937e966d383c4012c19b0e47dc196ba505eb19;p=linux-beck.git isci: Removed sci_base_object from scic_sds_remote_device. The 'struct sci_base_object' was removed from the struct scic_sds_remote_device.
