We get a few warnings when building kernel with W=1: drivers/isdn/mISDN/layer2.c:120:1: warning: no previous declaration for 'l2headersize' [-Wmissing-declarations] drivers/isdn/mISDN/layer2.c:127:1: warning: no previous declaration for 'l2addrsize' [-Wmissing-declarations] drivers/isdn/mISDN/layer2.c:379:1: warning: no previous declaration for 'cansend' [-Wmissing-declarations] drivers/isdn/mISDN/layer2.c:679:1: warning: no previous declaration for 'stop_t200' [-Wmissing-declarations] ....
In fact, these functions are only used in the file in which they are declared and don't need a declaration, but can be made static. So this patch marks these functions with 'static'.
