[PATCH] USB usblp: rate-limit printer status error messages
Rate-limit usblp printer error status messages. I unplugged my USB printer and almost instantly got several hundred of these in my kernel message log: drivers/usb/class/usblp.c: usblp0: error -19 reading printer status Signed-off-by: Randy Dunlap <rdunlap@xenotime.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
