[PATCH 22/38] media: dvb-ttusb-budget: cleanup printk logic

[Mauro Carvalho Chehab <mchehab+huawei@kernel.org>]

Instead of calling printk(), use pr_foo() macros.

While here, do some cleanup at the printed messages, as some
has __func__, while others have the module name (sometimes
spelled as "ttusb_dvb").
