From a6bb1bcebced1eeed6a96f37cda7cbb7cbd6dae6 Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Tue, 27 Jul 2010 13:03:46 -0700 Subject: [PATCH] libertas: convert CMD_FWT_ACCESS to a direct command Slightly different approach here since there are so many arguments to the firmware command. Just let the caller fill them in before pushing the command to the firmware. Signed-off-by: Dan Williams Signed-off-by: John W.
