[media] gspca: make arrays static, reduces object code size
Don't populate const arrays on the stack, instead make them static. Makes the object code smaller by over 5200 bytes: Before: text data bss dec hex filename 58259 8880 128 67267 106c3 ov519.o After: text data bss dec hex filename 52155 9776 128 62059 f26b ov519.o Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
