[PATCH] media: cxd2820r: make array tab static const, makes object smaller

From: Colin King
Date: Thu Sep 05 2019 - 13:45:18 EST


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

Don't populate the array tab on the stack but instead make it
static const. Makes the object code smaller by 53 bytes.

Before:
text data bss dec hex filename
7045 1736 0 8781 224d media/dvb-frontends/cxd2820r_c.o

After:
text data bss dec hex filename
6896 1832 0 8728 2218 media/dvb-frontends/cxd2820r_c.o

(gcc version 9.2.1, amd64)
