Commit 42a2f66 ("staging: vc04_services: Move global g_state to vchiq_state") changed mmal_init to pass dev->v4l2_dev.dev to vchiq_mmal_init, however nothing iniitialised dev->v4l2_dev, so we got a NULL pointer dereference. Set dev->v4l2_dev.dev during bcm2835_mmal_probe. The device pointer could be passed into v4l2_device_register to set it, however that also has other effects that would need additional changes. Fixes: 42a2f66 ("staging: vc04_services: Move global g_state to vchiq_state") Signed-off-by: Dave Stevenson <[email protected]>
