No need for curly braces here. I would not care if not for below.

Sorry I did not notice this before, but idev->keycode is devm-managed,
so you either need to use devm_kfree() or just remove call to kfree()
and let it clean up automatically (which will happen if binding fails or
upon removal).

BTW, maybe you should move the whole driver to devm_*? We have
devm_kzalloc() for ckdev and you can use devm_input_allocate_device().
Then you can get rid of entire erro handling path and completely remove
the remove() method as well.
 

+fail_matrix:
+	input_free_device(idev);
+fail_alloc_dev:
+	kfree(ckdev);
+	return err;
+}

Thanks.
