Our current code looks like nonseekable_open() is checked for the return

Bluetooth: hci_ldisc: fix NULL-pointer dereference on tty_close
Do not close protocol driver until device has been unregistered.
This fixes a race between tty_close and hci_dev_open which can result in
a NULL-pointer dereference.
The line discipline closes the protocol driver while we may still have
hci_dev_open sleeping on the req_lock mutex resulting in a NULL-pointer
dereference when lock is acquired and hci_init_req called.
Bug is 100% reproducible using hciattach and a disconnected serial port:

3. hci_dev_open is called from hci_sock_ioctl and sleeps on req lock
4. hci_uart_tty_close detaches protocol driver and cancels init req
5. hci_dev_open (1) releases req lock

8. hci_dev_open (3) grabs req lock, calls hci_init_req and eventually sleeps

Bluetooth: hci_ldisc: fix NULL-pointer dereference on tty_close
Do not close protocol driver until device has been unregistered.
This fixes a race between tty_close and hci_dev_open which can result in
a NULL-pointer dereference.
The line discipline closes the protocol driver while we may still have
hci_dev_open sleeping on the req_lock mutex resulting in a NULL-pointer
dereference when lock is acquired and hci_init_req called.
Bug is 100% reproducible using hciattach and a disconnected serial port:
0. # hciattach -n ttyO1 any noflow
1. hci_dev_open called from hci_power_on grabs req lock
2. hci_init_req executes but device fails to initialise (times out
eventually)
3. hci_dev_open is called from hci_sock_ioctl and sleeps on req lock
4. hci_uart_tty_close detaches protocol driver and cancels init req
5. hci_dev_open (1) releases req lock
6. hci_dev_open (3) grabs req lock, calls hci_init_req, which triggers oops
when request is prepared in hci_uart_send_frame

Bluetooth: Remove redundant hdev->parent field
We initialize the "struct device" in hci_alloc_dev() for a long time now
so we can access hdev->dev.parent directly. Hence, we can drop the
temporary field hdev->parent which is used in no other place than
hci_add_sysfs().
SET_HCIDEV_DEV() is never called after registering a device by the
drivers so we do not overwrite internal device-state. Furthermore,
hdev->dev is initialized to 0 by kzalloc() inside hci_alloc_dev() so the
default behavior with dev.parent = NULL is kept.

rtlwifi: rtl8192ce: rtl8192cu: rtl8192de: Fix low-gain setting when scanning
In https://bugzilla.redhat.com/show_bug.cgi?id=770207, slowdowns of driver
rtl8192ce are reported. One fix (commit
a9b89e2 ) has already been applied,
and it helped, but the maximum RX speed would still drop to 1 Mbps. As in
the previous fix, the initial gain was determined to be the problem; however,
the problem arises from a setting of the gain when scans are started.
Driver rtl8192de also has the same code structure - this one is fixed as well.
