used to control the backlight brightness. On systems without one, the
Crystal Cove SoC's PWM is used and we need to call pwm_add_table() so
that the i915 driver can find the pwm for controlling the backlight.

If the netdev is accessed before the urbs are initialized,
there will be NULL pointer dereferences. That is avoided by
registering it when it is fully initialized.
This case occurs e.g. if dhcpcd is running in the background
and the device is probed, either after insmod hso or
when the device appears on the usb bus.
A backtrace is the following:

On slave list updates, the bonding driver computes its hard_header_len
as the maximum of all enslaved devices's hard_header_len.
If the slave list is empty, e.g. on last enslaved device removal,
ETH_HLEN is used.
Since the bonding header_ops are set only when the first enslaved
device is attached, the above can lead to header_ops->create()
being called with the wrong skb headroom in place.
If bond0 is configured on top of ipoib devices, with the
following commands:
ifup bond0
for slave in $BOND_SLAVES_LIST; do
ip link set dev $slave nomaster
done
ping -c 1 <ip on bond0 subnet>
we will obtain a skb_under_panic() with a similar call trace:

This change addresses the issue avoiding updating the bonding device
hard_header_len when the slaves list become empty, forbidding to
shrink it below the value used by header_ops->create().
The bug is there since commit 54ef31371407 ("[PATCH] bonding: Handle large
hard_header_len") but the panic can be triggered only since
commit fc791b633515 ("IB/ipoib: move back IB LL address into the hard
header").

ACPICA commit c04d310039d3e0ed1cb62876fe7e596fbc75ab01
ACPICA commit a65c1df7e6b4bad8e37df822018c40c6c446add9
The key feature of this utility is that the original comments within
the input ASL files are preserved during the conversion process, and
included within the converted ASL+ file -- thus creating a transparent
conversion of existing ASL files to ASL+ (ASL 2.0)
This patch is an automatic generation of the ASL converter commit,
Linux kernel isn't affected by the functionality provided in this
commit, but requires the linuxized changes to support future ACPICA
release automation.

Tony Lindgren reports a kernel oops that resulted from my compile-time
fix on the default config. This shows two problems:
a) configurations that did not already enable PTP_1588_CLOCK will
now miss the cpts driver
b) when cpts support is disabled, the driver crashes. This is a
preexisting problem that we did not notice before my patch.
While the second problem is still being investigated, this modifies
the dependencies again, getting us back to the original state, with
another 'select NET_PTP_CLASSIFY' added in to avoid the original
link error we got, and the 'depends on POSIX_TIMERS' to hide
the CPTS support when turning it on would be useless.

Commit c49c097610fe ("ipmi: Don't call receive handler in the
panic context") means that the panic_recv_free is not called during a
panic and the atomic count does not drop to 0.
Fix this by only expecting one decrement of the atomic variable
which comes from panic_smi_free.
