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

From: Adrian Bunk
Date: Sun Jan 22 2006 - 12:09:22 EST



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.
