From: Baoyou Xie <[email protected]> We get 1 warning when building kernel with W=1: drivers/phy/tegra/xusb.c:104:5: warning: no previous prototype for 'tegra_xusb_lane_lookup_function' [-Wmissing-prototypes]
In fact, this function is only used in the file in which it is declared and don't need a declaration, but can be made static. So this patch marks it 'static'.
