This removes a warning on non-DT-enabled platforms:
drivers/leds/leds-pwm.c: In function 'led_pwm_create_of':
drivers/leds/leds-pwm.c:88:22: warning: unused variable 'node'
Really caused by the local variable that is assigned to and then never
used. Just do away with the local var, it's not needed.
Technically this code path can never be entered without DT enabled,
since there's an earlier check about number of children in the calling
function, but the compiler can't see that.

Overflow maybe occurs when calculates the duty time. For instance,
the period time is 990000000ns, and the max_brightness is 127, when
setting the brightness to 12, the duty value will be 25906026ns, but
it should be 93543307ns.

There are two ways to run a pattern in LP5523.
One is using legacy sysfs files such as 'enginex_mode','enginex_load' and
'enginex_leds'. ('x' is from 1 to 3).
Among them, 'enginex_leds' are used for selecting specific LED channel MUX.
(MUX means which LEDs are used for running a pattern from LED 1 to 9.)
The other way is using the firmware interface.
In this mode, the default LED MUX strings are used.
In other words, LED MUX is not configurable on the fly.
This patch enables dynamic LED MUX configuration when the firmware is loaded.
By accessing the sysfs file 'enginex_leds', the LED channels can be configured.
To synchronize the operation mode, each engine mode should be set to 'LOAD'.
The documentation is updated as well.

Whenever the engine is loaded by the user-application, the operation mode is
reset first. But it has a problem in case of multiple engine used because
previous engine settings are cleared.
The driver should update not whole 8bits but each engine bit by masking.
On the other hands, whole engines should be reset when the driver is unloaded
and on initializing the LP5523 driver.
So, new functions are used for this handling - lp5521/5523_stop_all_engines().

The 7 lines driven by the TCA6507 can either drive LEDs or act as output-only

To make this distinction in devicetree we use the "compatible" property.
If the device attached to a line is "compatible" with "gpio", we treat it
like a GPIO. If it is "compatible" with "led" (or if no "compatible" value
is set) we treat it like an LED.

1/ The led_info array must be allocated to allow the full number
of LEDs even if not all are present. The array maybe be sparsely
filled but it is indexed by device address so we must at least
allocate as many slots as the highest address used. It is easiest
just to allocate all 7.
2/ range check the 'reg' value properly.
3/ led.flags must be initialised to zero, else all leds could
be treated as GPIOs (depending on what happens to be on the stack).

But there are many more, resulting in the machine going OOM after some

From looking at the TPROXY code, and with help from Florian, I see
that the memory leak is introduced in tcp_v4_early_demux():
void tcp_v4_early_demux(struct sk_buff *skb)
{
/* ... */
iph = ip_hdr(skb);
th = tcp_hdr(skb);
if (th->doff < sizeof(struct tcphdr) / 4)
return;
sk = __inet_lookup_established(dev_net(skb->dev), &tcp_hashinfo,
iph->saddr, th->source,
iph->daddr, ntohs(th->dest),
skb->skb_iif);
if (sk) {
skb->sk = sk;
where the socket is assigned unconditionally to skb->sk, also bumping
the refcnt on it. This is problematic, because in our case the skb
has already a socket assigned in the TPROXY target. This then results
in the leak I see.
The very same issue seems to be with IPv6, but haven't tested.

Instead of relying on pool fields in ceph_file_layout (for mapping) and
ceph_pg (for enconding), start using ceph_object_locator (oloc)
abstraction. Note that userspace oloc currently consists of pool, key,
nspace and hash fields, while this one contains only a pool. This is
OK, because at this point we only send (i.e. encode) olocs and never
have to receive (i.e. decode) them.
This makes keeping a copy of ceph_file_layout in every osd request
unnecessary, so ceph_osd_request::r_file_layout field is nuked.

It happens because in bond_ab_arp_probe() we change the flags of a slave
without holding the RTNL lock.
To fix this - remove the useless curr_active_lock, RCUify it and lock RTNL
while changing the slave's flags. Also, remove bond_ab_arp_probe() from
under any locks in bond_ab_arp_mon().

Currently we're calling it from under RCU context, however we're using some
functions that require rtnl to be held.
Fix this by restructuring the locking - don't call it under any locks,
aquire rcu_read_lock() if we're sending _only_ (i.e. we have the active
slave present), and use rtnl locking otherwise - if we need to modify
(in)active flags of a slave.

Currently bond_ab_arp_probe() is always called under rcu_read_lock(),

To remove that curr_slave_lock - rcu_dereference the bond's
curr_active_slave and use it further - so that we're sure the slave won't
go away, and we don't care if it will change in the meanwhile.

As a result, a dev_WARN_ONCE will be hit during shutdown for every bnx2x

Currently we report through our error state only the rings that have
been initialised (as detected by ring->obj). This check is done after
the GPU reset and ring re-initialisation, which means that the software
state may not be the same as when we captured the hardware error and we
may not print out any of the vital information for debugging the hang.
This (and the implied object leak) is a regression from
commit 3d57e5bd12

drm/i915: Do a fuller init after reset
Note that we are already starting to get bug reports with incomplete
error states from 3.13, which also hampers debugging userspace driver
issues.
v2: Prevent a NULL dereference on 830gm/845g after a GPU reset where
the scratch obj may be NULL.

Microblaze without MMU can use stack protection in bootloader
and kernel should clear this setting ASAP.
