From: Márton Németh<nm...@freemail.hu>
Make the local variables and functions static. Some of them are not exported by
their
symbol name but used trough other means. For example a pointer of the operation
structure is passed through a function call.
This will remove the following sparse warnings (see "make C=1"):
* pd-video.c:20:5: warning: symbol 'usb_transfer_mode' was not declared.
Should it be static?
* pd-video.c:621:5: warning: symbol 'fire_all_urb' was not declared. Should
it be static?
* pd-video.c:881:5: warning: symbol 'vidioc_s_std' was not declared. Should
it be static?
* pd-video.c:1024:5: warning: symbol 'vidioc_g_audio' was not declared.
Should it be static?
* pd-video.c:1033:5: warning: symbol 'vidioc_s_audio' was not declared.

thanks. But Do you check the patch by script ./scripts/checkpatch.pl.
This line will
