PS22, Line 123: 	p = (void *)((uintptr_t)mc + sizeof(*mc));
If you want to do something like this, please use

p = mc->channel;

or

p = &mc->channel[0];

instead of raw address arithmetic.

PS22, Line 131: 		++p;
Please don't run two variables through the same loop unless really necessary. In this case, you can either write

for (p = mc->channel; p < &mc->channel[mc->num_channels]; p++)

or you just access `mc->channel[i].density` inside the loop and then you won't have any of these headaches from trying to get a pointer to the channel struct.
