linux-toradex.git/drivers/bluetooth/hci_bcm.c, branch v4.9.108 Linux kernel for Apalis and Colibri modules Bluetooth: hci_bcm: add missing tty-device sanity check 2017-05-20T12:28:41+00:00 Johan Hovold johan@kernel.org 2017-03-29T16:15:27+00:00 f2f6d77fabe250965b3a5a097ccea7766db0a457 commit 95065a61e9bf25fb85295127fba893200c2bbbd8 upstream. Make sure to check the tty-device pointer before looking up the sibling platform device to avoid dereferencing a NULL-pointer when the tty is one end of a Unix98 pty.

commit 95065a61e9bf25fb85295127fba893200c2bbbd8 upstream.

Make sure to check the tty-device pointer before looking up the sibling
platform device to avoid dereferencing a NULL-pointer when the tty is
one end of a Unix98 pty.
