phy: stm32: use NULL instead of zero
devm_clk_get() and devm_reset_control_get() expect a const char *id for the last arg, but a value of zero was provided. This results in below sparse warning: drivers/phy/st/phy-stm32-usbphyc.c:330:42: warning: Using plain integer as NULL pointer drivers/phy/st/phy-stm32-usbphyc.c:343:52: warning: Using plain integer as NULL pointer Instead of zero, use NULL Reviewed-by: Amelie Delaunay <amelie.delaunay@st.com> Link: https://lore.kernel.org/r/20200708132809.265967-6-vkoul@kernel.org Signed-off-by: Vinod Koul <vkoul@kernel.org>
