V4L/DVB (3344c): Pci probing for stradis driver
- Pci probing functions added, some functions were rewritten. - Use PCI_DEVICE macro. - dev_ used for printing when pci_dev available. Signed-off-by: Jiri Slaby <jirislaby@gmail.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
