Subject: [2.6 patch] media/video/cx23885/: cleanups
This patch contains the following cleanups:
- make the following needlessly global code static:
- cx23885-core.c: struct cx23885_sram_channels[]
- cx23885-core.c: struct cx23887_sram_channels[]
- cx23885-core.c: cx23885_wakeup()
- cx23885-core.c: cx23885_sram_channel_setup()
- cx23885-core.c: cx23885_sram_channel_dump()
- cx23885-core.c: cx23885_risc_disasm()
- cx23885-core.c: cx23885_shutdown()
- cx23885-core.c: cx23885_reset()
- cx23885-core.c: cx23885_dev_unregister()
- cx23885-core.c: cx23885_risc_databuffer()
- cx23885-core.c: cx23885_risc_stopper()
- #if 0 the following unused functions:
- cx23885-core.c: cx23885_risc_buffer()
- cx23885-core.c: cx23885_cancel_buffers()
- remove the following unused EXPORT_SYMBOL's:
- cx23885-cards.c: cx23885_boards
- cx23885-i2c.c: cx23885_call_i2c_clients
