Since hid_connect() only cares about hiddev_connect() succeeding or failing, there is no need for this function to return an int and it can return a bool instead.
Suggested-by: Jiri Kosina <ji...@kernel.org> Signed-off-by: Luis de Bethencourt <lui...@osg.samsung.com> --- Hi, The suggestion to change the return type of the function was made in: https://lkml.org/lkml/2015/10/5/330 In relation to hiddev_connect() returning the wrong errno code.
