    USB serial: make USB device id constant · 7d40d7e8
    Németh Márton authored
    The id_table field of the struct usb_device_id is constant in <linux/usb.h>
    so it is worth to make the initialization data also constant.
    
    The semantic match that finds this kind of pattern is as follows:

    // <smpl>
    @r@
    disable decl_init,const_decl_init;
    identifier I1, I2, x;

    	struct I1 {
    	  ...
    	  const struct I2 *x;
    	  ...
    	};
    @s@
    identifier r.I1, y;
    identifier r.x, E;

    	struct I1 y = {
    	  .x = E,
    	};
