[PATCH] mt76: mt76x0e: make array mt76x0_chan_map static const, makes object smaller

From: Colin King
Date: Fri Sep 06 2019 - 08:19:38 EST


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

Don't populate the array mt76x0_chan_map on the stack but instead make it
static const. Makes the object code smaller by 80 bytes.

Before:
text data bss dec hex filename
7685 1192 0 8877 22ad mediatek/mt76/mt76x0/eeprom.o

After:
text data bss dec hex filename
7541 1256 0 8797 225d mediatek/mt76/mt76x0/eeprom.o

(gcc version 9.2.1, amd64)
