tty->index (named here as line) is set up in initialize_tty_struct.
The value is checked in get_tty_driver for the found driver as:
if (device < base || device >= base + p->num)
continue;
*index = device - base;
So index/line can never be more than driver->num. Hence remove this

Before 33dd474a, these were some kind of protection against race with
HUP. They were protected with port->tty_sem at the same time.
By that commit, the counting was switched to tty_port's one, but the
locking remained the old one. So the count was not protected by
any lock anymore.
The driver should not test whether it raced with HUP or not anyways.
With the new refcounted tty model, it just should proceed as nothing
happened because all needed info is still there. In respect to this,
let's drop the useless and unprotected tests (tty_port->count is
protected by tty_port->lock).

Commit 0adf3c746a introduced a regression
by making the ECDT validation test for ASUS hardware more restrictive.
The previous test used the dmi_name_in_vendors function which searches
a number of DMI fields, while the new test checked only the BIOS
vendor, which is known to not match on an ASUS F5GL laptop which
requires ECDT validation.
Add a rule to ec_dmi_table based on an alternative DMI pattern for
ASUS hardware as found elsewhere in the kernel.

Now that the security modules can decide whether they support the
dcache RCU walk or not it's possible to make selinux a bit more
RCU friendly. The SELinux AVC and security server access decision
code is RCU safe. A specific piece of the LSM audit code may not
be RCU safe.
This patch makes the VFS RCU walk retry if it would hit the non RCU
safe chunk of code. It will normally just work under RCU. This is
done simply by passing the VFS RCU state as a flag down into the
avc_audit() code and returning ECHILD there if it would have an issue.

Since now when bonding uses rx_handler, all traffic going into bond
device goes thru bond_handle_frame. So there's no need to go back into
bonding code later via ptype handlers. This patch converts
original ptype handlers into "bonding receive probes". These functions
are called from bond_handle_frame and they are registered per-mode.
Note that vlan packets are also handled because they are always untagged
thanks to vlan_untag()
Note that this also allows arpmon for eth-bond-bridge-vlan topology.
