From 113328306dbdfd5f146f257e447364dc66d025d4 Mon Sep 17 00:00:00 2001 From: Jason Baron Date: Mon, 27 Oct 2008 12:05:14 -0400 Subject: [PATCH] Driver core: fix 'dynamic_debug' cmd line parameter In testing 2.6.28-rc1, I found that passing 'dynamic_printk' on the command line didn't activate the debug code. The problem is that dynamic_printk_setup() (which activates the debugging) is being called before dynamic_printk_init() is called (which initializes infrastructure). Fix this by setting setting the state to 'DYNAMIC_ENABLED_ALL' in dynamic_printk_setup(), which will also cause all subsequent modules to have debugging automatically started, which is probably the behavior we want.
