[PATCH 3/3] drm/bridge: Return NULL instead of plain 0 in drm_dp_hpd_bridge_register() stub

[Nathan Chancellor <nathan@kernel.org>]

sparse complains:

  drivers/usb/typec/tcpm/qcom/qcom_pmic_typec.c: note: in included file:
  include/drm/bridge/aux-bridge.h:29:16: sparse: sparse: Using plain integer as NULL pointer

Return NULL to clear up the warning.
