commit 6cd2c7db (videomode: videomode_from_timing work) changed the name of
the function from videomode_from_timing() to videomode_from_timings().

commit 32ed6ef1 (videomode: create enum for videomode's display flags) changed
the 'data_flags' field in videomode structure to 'flags'

Drilling down, this is related to dynamic channel ce_count attribute

function. So remove the bogus write permission to get rid of the

A race condition exists when registering the first watchdog device.
Sequence of events:

- watchdog_register_device calls watchdog_dev_register
- watchdog_dev_register creates the watchdog misc device by calling
  misc_register.
  At that time, the matching character device (/dev/watchdog0) does not yet
  exist, and old_wdd is not set either.
- Userspace gets an event and opens /dev/watchdog
- watchdog_open is called and sets wdd = old_wdd, which is still NULL,
  and tries to dereference it. This causes the kernel to panic.

Seen with systemd trying to open /dev/watchdog immediately after
it was created.

Commit 8a965b3b ("mm, slab_common: Fix bootstrap creation of kmalloc
caches") introduced a regression that caused us to crash early during
boot.  The commit was introducing ordering of slab creation, making sure
two odd-sized slabs were created after specific powers of two sizes.

But, if any of the power of two slabs were created earlier during boot,
slabs at index 1 or 2 might not get created at all.  This patch makes
sure none of the slabs get skipped.

Tony Lindgren bisected this down to the offending commit, which really
helped because bisect kept bringing me to almost but not quite this one.

Unlike meta data server mounts which support multiple mount points to
the same server via struct nfs_server, data servers support a single connection.

Concurrent calls to setup the data server connection can race where the first
call allocates the nfs_client struct, and before the cache struct nfs_client
pointer can be set, a second call also tries to setup the connection, finds the
already allocated nfs_client, bumps the reference count, re-initializes the
session,etc. This results in a hanging data server session after umount.

Fix to return -ENOMEM in the irlap_open() error handling case instead
of 0(overwrite to 0 by bfin_sir_startup()), as done elsewhere in this
function.

of_mdiobus_register creates a phy_device even if get_phy_device failed
to create it previously. This causes indefinite polling on non-existent
PHYs. This fix makes of_mdio_register rely on get_phy_device to
properly create the device or fail otherwise.

The driver and firmware sync up through SYNC messages, and the
firmware's affirmative reply to these SYNC messages appears to be the
"Reset" indication received via the status interrupt endpoint.  Thus the
driver needs the status interrupt endpoint always active so that the
Reset indication can be received even if the netdev is closed, which is
the case right after device insertion.

If the Reset indication is not received by the driver, it continues
sending SYNC messages to the firmware, which crashes about 10 seconds
later and the device stops responding.

Some drivers (sierra_net) need the status interrupt URB
active even when the device is closed, because they receive
custom indications from firmware.  Add functions to refcount
the status interrupt URB submit/kill operation so that
sub-drivers and the generic driver don't fight over whether
the status interrupt URB is active or not.

A sub-driver can call usbnet_status_start() at any time, but
the URB is only submitted the first time the function is
called.  Likewise, when the sub-driver is done with the URB,
it calls usbnet_status_stop() but the URB is only killed when
all users have stopped it.  The URB is still killed and
re-submitted for suspend/resume, as before, with the same
refcount it had at suspend.

A rebranded Novatel E371 for AT&T's LTE bands.  qmi_wwan should drive this
device, while cdc_ether should ignore it.  Even though the USB descriptors
are plain CDC-ETHER that USB interface is a QMI interface.

be_close() followed by be_clear() is called as a part of cleanup in the
EEH/AER flow.  This patch stops TX in be_close() before cleaning/freeing
up the TX queues in be_clear(). This prevents be_xmit() from being called
while TX queues no longer exist.

While cleaning RX queues, the CQ DB may be rung several times (with rearm)
while waiting for the flush compl. Each CQ-notify with rearm can result in
an event. The EQ may get full resulting in a HW error.

Fix this by not re-arming the CQ while notifying a valid completion.
Also, there's no need to wait for 1ms after destroying RXQ, as the code in
be_rx_cq_clean() waits for the flush compl to arrive.
