drivers/sbus/: cleanups
This patch contains the following cleanups: - make the following needlessly global code static: - char/uctrl.c: uctrl_get_event_status() - char/uctrl.c: uctrl_get_external_status() - char/vfc_dev.c: struct vfc_dev_lst - char/vfc_dev.c: vfc_lock_device() - char/vfc_dev.c: vfc_unlock_device() - char/vfc_dev.c: vfc_captstat_reset() - char/vfc_dev.c: vfc_memptr_reset() - char/vfc_dev.c: vfc_csr_init() - char/vfc_dev.c: vfc_saa9051_init() - char/vfc_dev.c: init_vfc_hw() - char/vfc_dev.c: init_vfc_devstruct() - char/vfc_dev.c: init_vfc_device() - char/vfc_dev.c: vfc_get_dev_ptr() - char/vfc_dev.c: vfc_capture_start() - char/vfc_dev.c: vfc_capture_poll() - char/vfc_dev.c: vfc_port_change_ioctl() - char/vfc_dev.c: vfc_set_video_ioctl() - char/vfc_dev.c: vfc_get_video_ioctl() - char/vfc_i2c.c: vfc_i2c_wait_for_bus() - char/vfc_i2c.c: vfc_i2c_wait_for_pin() - char/vfc_i2c.c: vfc_i2c_xmit_addr() - char/vfc_i2c.c: vfc_i2c_xmit_byte() - char/vfc_i2c.c: vfc_i2c_recv_byte() - dvma.c: init_one_dvma() - remove an unused variable from a function: - char/uctrl.c: ts102_uctrl_init() - remove the following unused and empty function: - char/uctrl.c: uctrl_set_video() Signed-off-by: Adrian Bunk <bunk@kernel.org> Signed-off-by: David S.
