Subject: Bluetooth: hci-uart-bcsp: Use GFP_ATOMIC in open()
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=c063af346d89be16e38385e55e5630070d6fd512;p=~shefty%2Frdma-dev.git

Bluetooth: hci-uart-bcsp: 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.
