2018-01-05i40iw: Replace mdelay with msleep in i40iw_wait_pe_readyJia-Ju Bai1-1/+1
i40iw_wait_pe_ready is not called in an interrupt handler nor holding a spinlock. The function mdelay in it can be replaced with msleep, to reduce busy wait.

2017-12-22i40iw: Selectively teardown QPs on IP addr change eventShiraz Saleem1-1/+1
On IP address change event, all connected QPs are torn down irrespective of whether IP address is involved in a connection. Only teardown connections those source or destination address matches the netdev interface IP address being changed, and if they are on the same VLAN as the netdev.

2017-09-22i40iw: Prevent multiple netdev event notifier registrationsShiraz Saleem1-15/+17
Netdev event notifier registration/de-registration is not synchronized with a lock and there is a possibility of a duplicate registration of notifier before the unregister completes. Register netdev event notifiers during module init and de-register them at module exit. This avoids the need to tie the registration to first netdev client interface open and de-registration to last client interface close and the synchronization to achieve it. This also fixes a crash due to duplicate registration.

2017-06-20sched/wait: Rename wait_queue_t => wait_queue_entry_tIngo Molnar1-1/+1
Rename: wait_queue_t => wait_queue_entry_t 'wait_queue_t' was always a slight misnomer: its name implies that it's a "queue", but in reality it's a queue *entry*. The 'real' queue is the wait queue head, which had to carry the name. Start sorting this out by renaming it to 'wait_queue_entry_t'. This also allows the real structure name 'struct __wait_queue' to lose its double underscore and become 'struct wait_queue_entry', which is the more canonical nomenclature for such data types.

2016-12-13i40iw: Fix memory leak in CQP destroy when in resetMustafa Ismail1-6/+3
On a device close, the control QP (CQP) is destroyed by calling cqp_destroy which destroys the CQP and frees its SD buffer memory. However, if the reset flag is true, cqp_destroy is never called and leads to a memory leak on SD buffer memory. Fix this by always calling cqp_destroy, on device close, regardless of reset. The exception to this when CQP create fails. In this case, the SD buffer memory is already freed on an error check and there is no need to call cqp_destroy.
