usb: storage: Add usb_stor_dbg, reduce object size
Reduce the size of the objects by consolidating the duplicated USB_STORAGE into a single function. Add function usb_stor_dbg to emit debugging messages. Always validate the format and arguments. Reduce the number of uses of CONFIG_USB_STORAGE_DEBUG. Reduces size of objects ~7KB when CONFIG_USB_STORAGE_DEBUG is set. $ size drivers/usb/storage/built-in.o* text data bss dec hex filename 140133 55296 70312 265741 40e0d drivers/usb/storage/built-in.o.new 147494 55248 70296 273038 42a8e drivers/usb/storage/built-in.o.old Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
