Also, when enabling the watchdog device, only set the watchdog device
enable bit and do not touch other bits; depending on the chip type,

All OMAP IP blocks expect LE data, but CPU may operate in BE mode.
Need to use endian neutral functions to read/write h/w registers.
I.e instead of __raw_read[lw] and __raw_write[lw] functions code
need to use read[lw]_relaxed and write[lw]_relaxed functions.
If the first simply reads/writes register, the second will byteswap
it if host operates in BE mode.

Changes are trivial sed like replacement of __raw_xxx functions
with xxx_relaxed variant.

I just can't find any value in MODULE_ALIAS_MISCDEV(WATCHDOG_MINOR)
and MODULE_ALIAS_MISCDEV(TEMP_MINOR) statements.

Either the device is enumerated and the driver already has a module
alias (e.g. PCI, USB etc.) that will get the right driver loaded
automatically.

Or the device is not enumerated and loading its driver will lead to
more or less intrusive hardware poking. Such hardware poking should be
limited to a bare minimum, so the user should really decide which
drivers should be tried and in what order. Trying them all in
arbitrary order can't do any good.

On top of that, loading that many drivers at once bloats the kernel
log. Also many drivers will stay loaded afterward, bloating the output
of "lsmod" and wasting memory. Some modules (cs5535_mfgpt which gets
loaded as a dependency) can't even be unloaded!

If defining char-major-10-130 is needed then it should happen in
user-space.

of_match_ptr() is a macro used to avoid undefined reference error if
CONFIG_OF is used to selectively compile in or out the
data structure. It is defined as follows:

#ifdef CONFIG_OF
#define of_match_ptr(ptr) ptr
#else
#define of_match_ptr(ptr) NULL
#endif

In the case of this series, none of the drivers use CONFIG_OF macro to
compile out the data structure (i.e., the data structure is always
defined).
Hence the use of of_match_ptr() does not make any sense. Thus removing
it to make the code look simpler for readability.

There seems to be some confusion here which functions return positive
numbers and which return negative error codes.

copy_to_user() returns the number of bytes remaining to be copied but we
want to return -EFAULT.

The rest is just clean up.  get_user() actually returns zero on success
and -EFAULT on error so we can preserve the error code.  The
timeout_to_regval() function returns -EINVAL on failure, but we can
propogate that back instead of hardcoding -EINVAL ourselves.

ASoC: Fixes for v3.13

A few fixes in drivers, the i.MX and wm8962 fixes are for a pretty nasty
issues for users of those drivers if they run into them.

We do not support SMB3 encryption yet, warn if server responds
that SMB3 encryption is mandatory.

Commit 7d02c4d6 ("iommu/shmobile: Enable the driver on all ARM
platforms") completely brokenly enabled the shmobile-iommu driver under
COMPILE_TEST.

It's bogus, because it won't compile anywhere else than ARM, since it
tries to include <asm/dma-iommu.h>, which is very much ARM-only.

So remove the bogus COMPILE_TEST dependency, which just causes
allmodconfig to fail on non-ARM platforms.

setfacl over cifs mounts can remove the default ACL when setting the
(non-default part of) the ACL and vice versa (we were leaving at 0
rather than setting to -1 the count field for the unaffected
half of the ACL.  For example notice the setfacl removed
the default ACL in this sequence:

steven@steven-GA-970A-DS3:~/cifs-2.6$ getfacl /mnt/test-dir ; setfacl
-m default:user:test:rwx,user:test:rwx /mnt/test-dir
getfacl: Removing leading '/' from absolute path names
user::rwx
group::r-x
other::r-x
default:user::rwx
default:user:test:rwx
default:group::r-x
default:mask::rwx
default:other::r-x
