Bluetooth: Remove unused h4_check_data_len() function

2013-10-11T05:51:09+00:00

The function h4_check_data_len() is actually not used. So just
remove it.

Bluetooth: Fix H4 crash from incoming UART packets

2013-04-04T09:35:58+00:00

This patch adds a check HCI_UART_REGISTERED before reading UART data in
the HCI UART H4 driver. UART data could arrive when inside the
hci_uart_tty_ioctl function after calling test_and_set_bit for
HCI_UART_PROTO_SET but before the hci_uart_set_proto function has
returned.

Bluetooth: hci-uart-h4: Use GFP_ATOMIC in open()

2012-02-13T15:01:22+00:00

The uart_proto open() callback is not called in atomic context so we can safely
sleep here. The caller hci_uart_set_proto() in hci_ldisc.c is an ioctl-handler
and therefore can sleep.

Bluetooth: Check return value of hci_recv_stream_fragment()

It may return error and in this case we do add to the stats.

Bluetooth: Enable per-module dynamic debug messages

2008-11-30T11:17:28+00:00

With the introduction of CONFIG_DYNAMIC_PRINTK_DEBUG it is possible to
allow debugging without having to recompile the kernel. This patch turns
all BT_DBG() calls into pr_debug() to support dynamic debug messages.

As a side effect all CONFIG_BT_*_DEBUG statements are now removed and
some broken debug entries have been fixed.
