media: ov9640: make const arrays res_x/y static const, reduces object code size
Don't populate the arrays res_x and resy_y on the stack, instead make them static const. Makes the object code smaller by over 160 bytes: Before: text data bss dec hex filename 10509 2800 64 13373 343d ov9640.o After: text data bss dec hex filename 10184 2960 64 13208 3398 ov9640.o Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Hans Verkuil <hansverk@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
