Staging: batman-adv: Wrapper functions for sysfs storing

Sysfs configuration options that just took a boolean value
(enable(d)/disable(d)/0/1) and integer setting basically all had the same
structure.

To avoid even more copy and pasting in the future and to make introducing
new configuration parameters for batman-adv simpler, more generic
wrapper functions are being introduced with this commit. They can deal with
boolean and unsigned integer parameters, storing them in the specified
atomic_t variables.

Staging: batman-adv: Unify sysfs file names with their bat_priv atomics

Both sysfs entries and variable names shall be as descriptive as
possible while not exceeding a certain length. This patch renames
bat_priv atomics to be equally descriptive with their according sysfs
entries.

Unifying sysfs and bat_priv atomic names also makes it easier to find
each others pendant.

The reduced ("type"-)information which was previously indicated with a
_enabled for booleans got substituted by a comment in bat_priv.

This patch has also been done in regards for the future BAT_ATTR_*
macros (they only need one name argument instead of a file and variable
name).

Staging: batman-adv: softif bridge loop avoidance

By connecting multiple batman-adv mesh nodes to the same ethernet
segment a loop can be created when the soft-interface is bridged
into that ethernet segment. A simple visualization of the loop
involving the most common case - a LAN as ethernet segment:

node1  <-- LAN  -->  node2
   |                   |
 wifi  <-- mesh -->  wifi

Packets from the LAN (e.g. ARP broadcasts) will circle forever from
node1 or node2 over the mesh back into the LAN.

This patch adds the functionality to detect other batman-adv nodes
connected to the LAN and select a 'gateway' to talk to the
non-batman-adv devices on this LAN. All traffic from and to the mesh
will be handled by this gateway to avoid the loop. OGMs received via
the soft-interface are interpreted as 'port announcements' to locate
potential batman-adv nodes. The patch can also deal with vlans on
top of batX and offers a list of LAN neighbors via debugfs.

Staging: bcm: signedness bug in StoreSFParam()

wrm() returns negative error codes so "ret" needs to be signed here.
There was place where wrm() returned positive EACCES instead of
negative -EACCES so I fixed that as well.  Also a few checkpatch.pl
issues.

Staging: iio/dds: double locking bugs

This is a static checker patch and I don't have this hardware.

This code is unusual because while I've often seen a double lock, this
is the first time I've seen code that takes a lock 11 times in a row.  I
feel like I must have missed something.  But I've looked very carefully
I don't see any way the original code is correct.  Does spi_sync()
somehow release the lock in a way that I can't see?  Even if it does,
the locking would still be wrong.

Looking at the code it was obvious what the problem was. The pointer
dpram_data was being allocated but the address was being written to.
Looking at the comment above the code shows that it use to write into an
element of that pointer where the '&' is appropriate. But now that it
writes to the pointer itself, we need to remove the '&' otherwise we
write over the pointer and not into the data it points to.

capabilities/syslog: open code cap_syslog logic to fix build failure

The addition of CONFIG_SECURITY_DMESG_RESTRICT resulted in a build
failure when CONFIG_PRINTK=n.  This is because the capabilities code
which used the new option was built even though the variable in question
didn't exist.

The patch here fixes this by moving the capabilities checks out of the
LSM and into the caller.  All (known) LSMs should have been calling the
capabilities hook already so it actually makes the code organization
better to eliminate the hook altogether.

  driver is ever looking for this value, so we can safely remove it.
