V4L/DVB (6595): Corrects printk lines
Make the driver less verbose by default. It adds a debug parameter to make the driver more verbose. Also, error messages were using KERN_ERR level, instead of KERN_INFO. A few printk messages were reviewed to make them more clear. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
