This patch contains the following possible cleanups:
- make needlessly global code static
- #if 0 the following unused global functions:
- b2c2/flexcop-dma.c: flexcop_dma_control_packet_irq()
- b2c2/flexcop-dma.c: flexcop_dma_config_packet_count()

Please review which of these changes do make sense and which conflict with pending patches.

dst is currently a bit broken ATM and there are quite a bit changes that haven't yet gone into linuxtv.org CVS tree. So i would be of the opinion, that if you can hold off on the patches to the dst/dst_ca module till it's fixed, that would be quite helpful.


Thanks,
Manu
