Most likely it is a sparse issue. Can you generate a minimal stand alone
test case that expose this bug? I try to simplify it as following, but
it does not
reproduce the error.
#define ARRAY_SIZE(x) (sizeof(x)/sizeof(x[0]))
static const char *v4l2_type_names[] = {
[1] = "mmap",
[9] = "userptr",
[2] = "overlay",
[3] = "dmabuf",
};
#define prt_names(a, arr) (((unsigned)(a)) < ARRAY_SIZE(arr) ? arr[a]
: "unknown")
extern void prt(const char *name);
static void v4l_print_requestbuffers(const void *arg, int write_only)
{
const struct v4l2_requestbuffers *p = arg;
prt(prt_names(3, v4l2_type_names));
}
If you have the test case, you are welcome to submit a patch to
add the test case.
