Subject: mei: nfc: fix memory leak in error path
From: Tomas Winkler <[email protected]>
commit 4bff7208f332b2b1d7cf1338e50527441283a198 upstream.
The flow may reach the err label without freeing cl and cl_info
cl and cl_info weren't assigned to ndev->cl and cl_info
so they weren't freed in mei_nfc_free called on error path
