[PATCH] drm/bridge/tc358767: make the array ext_div static const, makes object smaller

From: Colin King
Date: Thu Aug 19 2021 - 09:38:48 EST


From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

Don't populate the array ext_div on the stack but instead it
static const. Makes the object code smaller by 118 bytes:

Before:
text data bss dec hex filename
39449 17500 128 57077 def5 ./drivers/gpu/drm/bridge/tc358767.o

After:
text data bss dec hex filename
39235 17596 128 56959 de7f ./drivers/gpu/drm/bridge/tc358767.o

(gcc version 10.3.0)
