Subject: [PATCH] Bluetooth: hci-uart-ll: Use GFP_ATOMIC in open()
Date: Sat, 7 Jan 2012 15:19:37 +0100 [thread overview]
Message-ID: <1325945981-11330-1-git-send-email-dh.herrmann@googlemail.com> (raw)
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.
