drm/bridge: tda998x: Return NULL instead of 0 in tda998x_edid_read()
tda998x_edid_read() returns a const struct drm_edid pointer, but when tda998x_edid_delay_wait() fails (process killed while waiting for the HPD timeout), the integer literal 0 is returned instead of NULL, triggering a sparse warning: "Using plain integer as NULL pointer" Replace 0 with NULL to fix the sparse warning. Fixes: c76a8be4feec ("drm/bridge: tda998x: Add support for DRM_BRIDGE_ATTACH_NO_CONNECTOR") Reported-by: kernel test robot <lkp@intel.com> Closes: https://lore.kernel.org/oe-kbuild-all/202604172257.Imo6GOH9-lkp@intel.com/ Signed-off-by: Kory Maincent (TI) <kory.maincent@bootlin.com> Reviewed-by: Luca Ceresoli <luca.ceresoli@bootlin.com> Link: https://patch.msgid.link/20260417155446.1068893-1-kory.maincent@bootlin.com Signed-off-by: Luca Ceresoli <luca.ceresoli@bootlin.com>
