Interesting finding... the function needs to ensure mf->code is set
to one of supported values by the driver, so instead of removing
how about changing the above line to:
if (i < 0)
mf->code = camif_mbus_formats[0];
?
That would still have one of the two out-of-bounds accesses;-)
Ah, indeed :/
maybe this
for (i = 0; i < ARRAY_SIZE(camif_mbus_formats); i++)
if (camif_mbus_formats[i] == mf->code)
break;
if (i == ARRAY_SIZE(camif_mbus_formats))
mf->code = camif_mbus_formats[0];
Yes, it should work that way.
