Extern variables and functions used in only one file were removed from .h files, and made static in the .c files they're used. Extern variable wilc_initialized was declared and never used, so it was removed. Signed-off-by: Elise Lennion <elise.lennion@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
