tlg2300: make local variables and functions static
Commit Message
From: Márton Németh <nm127@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?
