From c3c2077d9579472b07581ecdaf6cc5a60b1700bc Mon Sep 17 00:00:00 2001 From: =?utf8?q?Antti=20Sepp=C3=A4l=C3=A4?= Date: Sun, 16 Feb 2014 07:16:02 -0300 Subject: [PATCH] [media] nuvoton-cir: Activate PNP device when probing MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit On certain motherboards (mainly Intel NUC series) bios keeps the Nuvoton CIR device disabled at boot. This patch adds a call to kernel PNP layer to activate the device if it is not already activated. This will improve the chances of the PNP probe actually succeeding on Intel NUC platforms.
