[PATCH] usb: renesas_usbhs: make array type_array static const

From: Colin King
Date: Tue Jul 04 2017 - 06:31:32 EST


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

Array type_array can be made static const rather than being
populated on the stack. Makes the object code smaller:

Before:
text data bss dec hex filename
8087 1496 0 9583 256f drivers/usb/renesas_usbhs/pipe.o

After:
text data bss dec hex filename
7883 1584 0 9467 24fb drivers/usb/renesas_usbhs/pipe.o
