bluetooth: hci_nokia: Don't include linux/unaligned/le_struct.h directly.

This breaks the build as this header is not meant to be used in this
way.

Bluetooth: hci_serdev: Move serdev_device_close/open into common hci_serdev code

2018-05-30T06:47:42+00:00

Make hci_uart_register_device() and hci_uart_unregister_device() call
serdev_device_close()/open() themselves instead of relying on the various
hci_uart drivers to do this for them.

Besides reducing code complexity, this also ensures correct error checking
of serdev_device_open(), which was missing in a few drivers.

Bluetooth: hci_uart: Restore hci_dev->flush callback on open()

2018-05-30T06:46:17+00:00

For reasons explained in detail in commit 3611f4d2a5e0 ("hci_ldisc:
fix null pointer deref") the hci_uart_close() functions sets
hci_dev->flush to NULL.

But the device may be re-opened after a close, this commit restores the
hci_dev->flush callback on open().

Note this commit also moves the nearly empty defition of hci_uart_open()
a bit down in the file to avoid the need for forward declaring
hci_uart_flush().

Bluetooth: hci_qca: Fix "Sleep inside atomic section" warning

2018-05-30T06:12:17+00:00

This patch fixes the following warning during boot:

 do not call blocking ops when !TASK_RUNNING; state=1 set at
 [<(ptrval)>] qca_setup+0x194/0x750 [hci_uart]
 WARNING: CPU: 2 PID: 1878 at kernel/sched/core.c:6135
 __might_sleep+0x7c/0x88

In qca_set_baudrate(), the current task state is set to
TASK_UNINTERRUPTIBLE before going to sleep for 300ms. It was then
restored to TASK_INTERRUPTIBLE. This patch sets the current task state
back to TASK_RUNNING instead.

Bluetooth: btmrvl: support sysfs initiated firmware coredump

2018-05-29T13:59:50+00:00

Since commit 3c47d19ff4dc ("drivers: base: add coredump driver ops")
it is possible to initiate a device coredump from user-space. This
patch adds support for it in btmrvl_sdio adding the .coredump()
driver callback. This makes dump through debugfs obsolete so removing
it.
