No. Only gspca branche have these problems. Because other braches 
return error over S_FMT ioctl, when pixelformat is unsupported by hardware.
But these behavior is not correspond with v4l2 specification.
See comment from Hans De Goede (author of original libv4l).

Gspca framework respect specification.

Bug is in applications! Application must verify returned pixelformat from S_FMT 
ioctl!
My edit of libv4l evade this bug.
