[RFC: 2.6 patch] drivers/media/dvb/: possible cleanups

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
