USB: usb-storage: trivial debug improvements
Use pr_foo and dev_foo instead of printk. Maybe US_DEBUG* should be replaced too. Signed-off-by: Felipe Contreras <felipe.contreras@gmail.com> Cc: Matthew Dharm <mdharm-usb@one-eyed-alien.net> Cc: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
