[PATCH] DVB flexcop-pci sanitize driver name to avoid warning on load

[Jindrich Makovicka <makovick@gmail.com>]

Hi,

DVB driver for Flexcop/Technisat receiver currently calls request_irq()
with a long driver name containing slashes. This triggers a warning
when kernel tries to create /proc/irq/[NN]/[driver name] directory
(attached to avoid mangling).

The patch in attachment changes the driver name used in
pci_request_regions() and request_irq() to a shorter version without
slashes.
