Please DO NOT ever put motor oil on your dog like the first poster suggested. This is a cruel, potentially fatal treatment, and only an idiot would suggest it. If I ever saw someone coat their dog in motor oil I would be calling the authorities for animal cruelty.
It could be the beginning of mange or it could be scabies. It could also be that he scratched his ears form fleas or mites and that causes it. You can contact your vet about med to give him
Flaky and dry skin is caused by scratching. This scratching in ears can be due to ear dermatitis. There are many conditions that can cause ear dermatitis. Following is list of some conditions that can cause ear dermatitis in dogs.
- Cushing's disease

It is one of a few things things. If it is cold where you live then it could be the cold affecting his skin. Try a shampoo like Main and Tails followed by the conditioner. Secondly it could be mange. There is an old rememedy for this that the old timers use to do back in the 1800's and early 1900's. Get some used motor oil and soak the dog in it. AVOID getting it in his face. Let it soak on him for approx 20 minutes. Then wash it off using regular Dawn dishwashing detergent. Within a week the fur should began to grow back. Thirdly, you could try a medicated shampoo recommended by your vet. It may just be what is called "hot spots" Some dogs have allergies and it affects their skin just like humans do. If you are not sure the best thing is to go to the vet.
