From: Takashi Iwai Date: Mon, 2 Dec 2013 14:38:17 +0000 (+0100) Subject: microcode: Use request_firmware_direct() X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=75da02b29fd99cb2d6ac822f2864de4d6e35b9fd;p=linux-beck.git microcode: Use request_firmware_direct() Use the new helper, request_firmware_direct(), for avoiding the lengthy timeout of non-existing firmware loads. Especially the Intel microcode driver suffers from this problem because each CPU triggers the f/w loading, thus it ends up taking (literally) hours with many cores.
