Subject: target: remove the se_obj_ptr and se_orig_obj_ptr se_cmd fields
X-Git-Tag: v3.2-rc5~31^2~18
X-Git-Url: https://git.openpandora.org/cgi-bin/gitweb.cgi?p=pandora-kernel.git;a=commitdiff_plain;h=58a2801a4b9ad97d3685bb7a3344e17d60292908

target: remove the se_obj_ptr and se_orig_obj_ptr se_cmd fields

We already have a perfectly valid se_device pointer in the command, so
remove the mostly useless duplicates.
