Subject: [PATCH 4.9 54/66] IB/rxe: Fix rxe dev insertion to rxe_dev_list

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Maor Gottlieb <maorg@...lanox.com>

commit f39f775218a7520e3700de2003c84a042c3b5972 upstream.

The first argument of list_add_tail is the new item and the second
is the head of the list. Fix the code to pass arguments in the
right order, otherwise not all the rxe devices will be removed
during teardown.

Fixes: 8700e3e7c4857 ('Soft RoCE driver')
