From: Edmund Nadolski Date: Thu, 5 May 2011 01:11:43 +0000 (+0000) Subject: isci: kill scic_controller_get_port_handle function X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ed30c275dd9fc5c603081144db5df3110f258534;p=linux-beck.git isci: kill scic_controller_get_port_handle function This function is just overkill and its usage is inconsistent. Replace with inlined code.
