Subject: Bluetooth: hci-uart-h4: Use GFP_ATOMIC in open()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=fdcd1661a6b22e3ac429759627d2b4d68f77d64a;p=mv-sheeva.git

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

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.
