[PATCH] fbdev: matrox: make array wtst_xlat static const, makes object smaller

[Colin King]

From: Colin Ian King <colin.king at canonical.com>

Don't populate the array wtst_xlat on the stack but instead make it
static const. Makes the object code smaller by 89 bytes.

Before:
   text	   data	    bss	    dec	    hex	filename
  14347	    840	      0	  15187	   3b53	fbdev/matrox/matroxfb_misc.o

After:
   text	   data	    bss	    dec	    hex	filename
  14162	    936	      0	  15098	   3afa	fbdev/matrox/matroxfb_misc.o

(gcc version 9.2.1, amd64)
