Subject: [PATCH net-next 11/14] ice: drop two params from ice_aq_alloc_free_res()
From: Przemek Kitszel <przemyslaw.kitszel@...el.com>
Drop @num_entries and @cd params, latter of which was always NULL.
Number of entities to alloc is passed in internal buffer, the outer layer
(that @num_entries was assigned to) meaning is closer to "the number of
requests", which was =1 in all cases.
ice_free_hw_res() was always called with 1 as its @num arg.
