Now that the last DSI PHY PLL driver (dsi_phy_28nm_8960) has been converted to use a simple stack-local char-array instead of a devm_kzalloc heap allocation we can safely call sizeof() on every string variable (that's now a sized array instead of a pointer) passed into snprintf instead of hardcoding the size.
