V4L/DVB (6575): 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 Signed-off-by: Adrian Bunk <bunk@kernel.org> Reviewed-by: Steven Toth <stoth@linuxtv.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
