Subject: [PATCH 0/4] dma-debug: driver filter v2

Hi,

this small patchset adds a new feature to dma-api debugging: a driver
filter. A driver developer can write the name of his driver to
dma-api/driver_filter and the kernel will then only print errors
produced by this driver. This is useful if other drivers in the system
also have bugs. In this case the driver developer can limit the bug
output to messages interesting for him.

	Joerg

Changes since v1:

	- addressed Andrews comments (used string functions were
	  appropriate and reduced inlining, added some more
	  comments)
