Propagate the return value of platform_get_irq on failure.
A simplified version of the semantic match that finds the two cases where
no error code is returned at all is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@@
identifier ret; expression e1,e2;
@@
(
if (\(ret < 0\|ret != 0\))
{ ... return ret; }
|
ret = 0
)
... when != ret = e1
when != &ret
*if(...)
{
... when != ret = e2
when forall
return ret;
}
// </smpl>

Commit 5b48bb8506c5 ("openvswitch: Fix helper reference leak") fixed a
reference leak on helper objects, but inadvertently introduced a leak on
the ct template.
Previously, ct_info.ct->general.use was initialized to 0 by
nf_ct_tmpl_alloc() and only incremented when ovs_ct_copy_action()
returned successful. If an error occurred while adding the helper or
adding the action to the actions buffer, the __ovs_ct_free_action()
cleanup would use nf_ct_put() to free the entry; However, this relies on
atomic_dec_and_test(ct_info.ct->general.use). This reference must be
incremented first, or nf_ct_put() will never free it.
Fix the issue by acquiring a reference to the template immediately after
allocation.

Ming Lei says:
====================
bpf: hash: use per-bucket spinlock
This patchset tries to optimize ebpf hash map, and follows
the idea:
Both htab_map_update_elem() and htab_map_delete_elem()
can be called from eBPF program, and they may be in kernel
hot path, it isn't efficient to use a per-hashtable lock
in this two helpers, so this patch converts the lock into
per-bucket spinlock.
With this patchset, looks the performance penalty from eBPF
decreased a lot, see the following test:
1) run 'tools/biolatency' of bcc before running block test;
2) run fio to test block throught over /dev/nullb0,
(randread, 16jobs, libaio, 4k bs) and the test box
is one 24cores(dual sockets) VM server:
- without patchset: 607K IOPS
- with this patchset: 1184K IOPS
- without running eBPF prog: 1492K IOPS
TODO:
- remove the per-hashtable atomic counter
V2:
- fix checking on buckets size
V1:
- fix the wrong 3/3 patch

so it isn't efficient to use a per-hashtable lock in this two
helpers.
The per-hashtable spinlock is used for protecting bucket's
hlist, and per-bucket lock is just enough. This patch converts
the per-hashtable lock into per-bucket spinlock, so that
contention can be decreased a lot.

The core st21nca module is useless without the I2C access module.
So hide NFC_ST21NFCA and select it automatically if either
NFC_ST21NFCA_I2C is selected.
This avoids presenting NFC_ST21NFCA when NFC_ST21NFCA_I2C can't be
selected.

dev->nr_luns reports the total number of luns available in a device
while dev->luns_per_chnl is the number of luns per channel.
When multiple channels are available, the offset is calculated from a
channel and lun id into a linear array. As it multiplies with
the total number of luns, we go out of bound when channel id > 0 and
causes the kernel to panic when we read a protected kernel memory area.

ioremapping multiple BARs produces a warning with a message "Your kernel is
fine". This message mostly serves to comfort kernel developers. Users do
not read the message, they only see the big scary warning which means
something must be horribly broken with their system. Less dramatically, the
warn also sets the taint flag which makes it difficult to differentiate
problems. If the kernel is actually fine as the warning claims it doesn't
make sense for it to be tainted. Change the WARN_ONCE to a pr_warn with the
caller of the ioremap.

Some OMAP interrupt controllers use generic level detection, so
handle_level_irq() is used as the chip type handler.
Allocated IRQ chip type handler doesn't need to set it again because

This commit adds support for the TS-4800 interrupt controller. This
controller is instantiated in a companion FPGA, and multiplex interrupts
for other FPGA IPs.
As this component is external to the SoC, the SoC might need to reserve
pins, so this controller is implemented as a platform driver and doesn't
use the IRQCHIP_DECLARE construct.
