From a351f2f537b711bed3d0f6a75d7e9fddcbe51ffe Mon Sep 17 00:00:00 2001 From: Lazar Alexei Date: Fri, 20 Jan 2017 13:49:45 +0200 Subject: [PATCH] wil6210: support loading dedicated image for sparrow-plus devices Driver may be used in platforms where some use sparrow cards while other use sparrow-plus cards, where different FW image is needed. Add the capability to load dedicated FW image in case sparrow-plus card is detected and fallback to default image if such does not exist.
