linux-toradex.git/drivers/char/ppdev.c, branch tegra-10.7.1 Linux kernel for Apalis and Colibri modules ppdev: reduce kernel log spam 2009-06-18T20:03:54+00:00 Michael Buesch mb@bu3sch.de 2009-06-17T23:27:49+00:00 81fc401e426e8a4c719035ef86d051bd0d1111e5 One of my programs frequently grabs the parport, does something with it and then drops it again. This results in spamming of the kernel log with "... registered pardevice" "... unregistered pardevice" These messages are completely useless, except for debugging ppdev, probably.

	- spi_butterfly (parent of spi_master, allowing cruft removal)
	- lp (creating class_device)
	- ppdev (parent of parportN device)
	- tipar (creating class_device)

There are still drivers that should be updated, like some of the input
drivers; but they won't be any worse off than they are today.
