Subject: Bluetooth: hci-uart-ll: Use GFP_ATOMIC in open()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9eb648c39af8c14cb63fc9ccfc9a52cdb4442daa;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

Bluetooth: hci-uart-ll: 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.
