phy: stm32: use NULL instead of zero (0ff35966) · Commits · 戴 / test

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:
