From e177123f0c2d77ed2fde724ca352166ca9464619 Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Sat, 13 Mar 2010 23:49:23 -0800 Subject: [PATCH] firmware loader: do not allocate firmare id separately fw_id has the same life time as firmware_priv so it makes sense to move it into firmware_priv structure instead of allocating separately.
