Subject: [PATCH 4.4 079/107] x86/bugs: Fix __ssb_select_mitigation() return type

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jiri Kosina <jkosina@...e.cz>

commit d66d8ff3d21667b41eddbe86b35ab411e40d8c5f upstream

__ssb_select_mitigation() returns one of the members of enum ssb_mitigation,
not ssb_mitigation_cmd; fix the prototype to reflect that.

Fixes: 24f7fc83b9204 ("x86/bugs: Provide boot parameters for the spec_store_bypass_disable mitigation")
