"do {} while()" does the job but "for()" would be better suitable:

for (planes_allowed = 0; planes_allowed < n_planes; planes_allowed++) {
	int err;

	prepare_planes(data, pipe, &blue, tiling, planes_allowed,
output);
	err = igt_display_try_commit2(&data->display, COMMIT_ATOMIC);
	if (err)
		break;
}


Also you are leaking a bunch o memory here, each call to
prepare_planes() will leak max_planes framebuffers, this could cause
test to fail due no GPU memory available.

Actually this test is already leaking a bunch as test_fini() is only
freeing the first framebuffer, there is other leaks here too like:
data->fb, prepare_planes().x, prepare_planes().y and
prepare_planes().size.

Can you take care of that too?

We actually want to fail the test if it can not even test one plane, so
add this before this while()

igt_assert_lt(0, planes_allowed);

I don't have strong preference on this issue. For such loops I normally 
use do{}..while() to make it certain loop is ran at least once in any 
situation and underline it for 'the next guy'.

Anyway your for loop wouldn't do the trick. I think it will become 
somewhat more complex and need different handling for 'all planes did 
work' and 'not all planes did work'. Loop cannot start with zero planes, 
then if n_planes is just one it will never be tested unless specially 
taken care of.

yea, I did see those in Valgrind already while writing this patch. 
Reason why I didn't go after them yet is below 'clean up failed state' 
is something I shouldn't need to do. Last commit in my loop can fail and 
IGT has mechanism to do cleaning, for some reason IGT mechanism misses 
it here. I want to find out how IGT lost the cleaning information and 
this test can show it to me.

On after thought checking here for zero is useless, I'll throw it away. 
If there was not a single plane this test would've asserted already 
during setup where it get reference crc.

This isn't enough, kernel might have other limits than just total number
of planes. In the future this might depend upon where they are actually
placed, how big, and all that stuff.

Also, we need to randomize which planes we pick, so needs an
igt_permute_array somewhere to avoid always using the same first planes.

I think that sound like new subtest for this test. This test does 
randomize placing of planes already though.

that sound like good idea, I'll include it into v2.
