V4L/DVB (9110): cx18: Add default behavior of checking and retrying PCI MMIO accesses
cx18: Add default behavior of checking and retrying PCI MMIO accesses.
The concept of checking and retrying PCI MMIO accesses for better reliability
in older motherboards was suggested by Steve Toth <stoth@linuxtv.org>. This
change implements MMIO retries and the retry_mmio module parameter that is
enabled by default. Limited experiments have shown this is more reliable than
the mmio_ndelay parameter. mmio_ndelay has insignificant effect with retries
enabled.
