+Subject: [PATCH] phy: phy-brcm-usb: Constify static structs
+
+A number of structs were not modified and can therefore be made const
+to allow the compiler to put them in read-only memory.
+
+In order to do so, update a few functions that don't modify there input
+to take pointers to const.
+
+Before:
+   text    data     bss     dec     hex filename
+  15511    6448      64   22023    5607 drivers/phy/broadcom/phy-brcm-usb.o
+
+After:
+   text    data     bss     dec     hex filename
+  16058    5936      64   22058    562a drivers/phy/broadcom/phy-brcm-usb.o
