From: Colin King
Date: Fri Sep 06 2019 - 08:49:48 EST


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

Don't populate the array serdes_reg on the stack but instead make it
static const. Makes the object code smaller by 228 bytes.

Before:
text data bss dec hex filename
23875 6232 64 30171 75db drivers/phy/phy-xgene.o

After:
text data bss dec hex filename
23551 6328 64 29943 74f7 drivers/phy/phy-xgene.o

(gcc version 9.2.1, amd64)
