In bcm2835_fb_mbox_push(), Coverity complains (CID 1429989) that we
pass a pointer to a local struct to another function without
initializing all its fields. This is a real bug:
bcm2835_fb_reconfigure() copies the whole of our new BCM2385FBConfig
struct into s->config, so any fields we don't initialize will corrupt
the state of the device.
Copy the two fields which we don't want to update (pixo and alpha)
from the existing config so we don't accidentally change them.
Fixes:
