From 72dcc883d8e5b59105e75ee5265442e458740575 Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Mon, 28 Apr 2008 16:34:07 -0600 Subject: PNP: add debug output to encoders Add debug output to encoders (enabled by CONFIG_PNP_DEBUG). This uses dev_printk, so I had to add pnp_dev arguments at the same time.
