But if an interrupt already occurred the\ninterrupt handler will be waiting for the mpc_lock and free_irq() will\ndeadlock waiting for the handler to finish.\n\nThis issue is similar to the one fixed in commit 7dd9c26bd6cf (\"can:\nmcp251x: fix deadlock if an interrupt occurs during mcp251x_open\") but\nfor the error path.\n\nTo solve this issue move the call to free_irq() after the lock is\nreleased.
