Subject: [PATCH] drm/mgag200: make a const array static, makes object smaller
Date: Thu,  4 Feb 2021 18:17:56 +0000	[thread overview]
Message-ID: <20210204181756.109549-1-colin.king@canonical.com> (raw)

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

Don't populate the const array m_div_val on the stack but instead make
it static. Makes the object code smaller by 29 bytes:

Before:
   text	   data	  bss   dec    hex filename
  34736	   4552	    0 39288   9978 drivers/gpu/drm/mgag200/mgag200_mode.o

After:
   text	   data	  bss   dec    hex filename
  34625	   4616	    0 39241   9949 drivers/gpu/drm/mgag200/mgag200_mode.o

(gcc version 10.2.0)
