4.14-stable review patch. If anyone has any objections, please let me know.
------------------ From: Gustavo A. R. Silva <[email protected]> commit 060d0bf491874daece47053c4e1fb0489eb867d2 upstream. There is a potential NULL pointer dereference in case devm_kzalloc() fails and returns NULL. Fix this by adding a NULL check on rt5514_dsp. This issue was detected with the help of Coccinelle.
