Re: [PATCH 6/6] phy: stm32: use NULL instead of zero

Hi Vinod,

On 7/8/20 3:28 PM, Vinod Koul wrote:

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
