Pull GPIO fixes from Linus Walleij:
"Here are a few GPIO fixes for v4.8.
I was expecting some fallout from the new chardev rework but nothing
like that turned up att all. Instead a Kconfig confusion that I think
I have finally nailed, then some ordinary driver noise and trivia.
This fixes a Kconfig issue with UM: when I made GPIOLIB available to
all archs, that included UM, but the OF part of GPIOLIB requires
HAS_IOMEM, so we add HAS_IOMEM as a dependency to OF_GPIO.
This in turn exposed the fact that a few GPIO drivers were implicitly
assuming OF_GPIO as their dependency but instead depended on OF alone
(the typical problem being a pointer inside gpio_chip not existing
unless OF_GPIO is selected) and then UM would fail to compile with
these drivers instead. Then I lost patience and made any GPIO driver
depending on just OF depend on OF_GPIO instead, that is certainly what
they meant and the only thing that makes sense anyway. GPIO with just
OF but !OF_GPIO does not make sense.
Also a fix for the max730x driver data pointer, and a minor comment
fix for the GPIO tools"

The silead code is using devm_foo for everything (and does not free
any resources). Except that it is using gpiod_get instead of
devm_gpiod_get (but is not freeing the gpio_desc), change this
to use devm_gpiod_get so that the gpio will be properly released.

The i40iw initiator sends an MPA-request with ird=16 and ord=16. The cxgb4
responder sends an MPA-reply with ord = 32 causing i40iw to terminate
due to insufficient resources.

The i40iw initiator sends an MPA-request with ird = 63, ord = 63. The
cxgb4 responder sends a RST. Since the inbound ord=63 and it exceeds
the max_ird/c4iw_max_read_depth (=32 default), chelsio decides to abort.
Instead, cxgb4 should adjust the ord/ird down before presenting it to
the ULP.

Testing with CONFIG_SLUB_DEBUG_ON=y resulted in the kernel panic below.
This is the result of the mm_struct sometimes being free'd prior to
hfi1_file_close being called.
This was due to the combination of 2 reasons:
1) hfi1_file_close is deferred in process exit and it therefore may not
be called synchronously with process exit.
2) exit_mm is called prior to exit_files in do_exit. Normally this is ok
however, our kernel bypass code requires us to have access to the
mm_struct for house keeping both at "normal" close time as well as at
process exit.
Therefore, the fix is to simply keep a reference to the mm_struct until
we are done with it.

The unwind logic for creating a user QP has a double vfree
of the non-shared receive queue when handling a "too many qps"
failure.
The code unwinds the mmmap info by decrementing a reference
count which will call rvt_release_mmap_info() which in turn
does the vfree() of the r_rq.wq. The unwind code then does
the same free.
Fix by guarding the vfree() with the same test that is done
in close and only do the vfree() if qp->ip is NULL.

Previously, J_KEY generation was based on the lower 16 bits
of the user's UID. While this works, it was not good enough
as a non-root user could collide with a root user given a
sufficiently large UID.
This patch attempt to improve the J_KEY generation by using
the following algorithm:
The 16 bit J_KEY space is partitioned into 3 separate spaces
reserved for different user classes:
* all users with administtor privileges (including 'root')
will use J_KEYs in the range of 0 to 31,
* all kernel protocols, which use KDETH packets will use
J_KEYs in the range of 32 to 63, and
* all other users will use J_KEYs in the range of 64 to
65535.
The above separation is aimed at preventing different user levels
from sending packets to each other and, additionally, separate
kernel protocols from all other types of users. The later is meant
to prevent the potential corruption of kernel memory by any other
type of user.

when a cat of the qp_stats is done:

[ 231.766862]
The init functions do an implicit next which requires the rcu read lock
before the kzalloc().
Fix for both drivers is to change the scope of the init function to only
do the allocation and the initialization of the just allocated iter.
The implict next is moved back into the respective start functions to fix
the issue.

Error code EAGAIN should be used when errors are temporary and next call
might succeeds.
When error code other than EAGAIN is returned, the caller (mlx4_ib_poll)
will assume all CQE in the same bunch are error too and will drop them all.

We were using the same mask twice. Looking at radeon, it seems
we should be using HDMI_AVI_INFO_CONT instead as the second mask.
Being there, fix typos in comments and improved readability.
I haven't looked at other DCEs, the mask may also be wrong for them.

The cec-funcs.h header was missing support for these three vendor-specific messages:
CEC_MSG_VENDOR_COMMAND
CEC_MSG_VENDOR_COMMAND_WITH_ID
CEC_MSG_VENDOR_REMOTE_BUTTON_DOWN
Add wrappers for these messages.
I originally postponed adding these wrappers due to the fact that the argument is
just a byte array which cec-ctl couldn't handle at the time, and then I just forgot
to add them once the CEC framework was finalized.
It wasn't until an attempt to transmit a vendor specific command was made that I
realized that these wrappers were missing.

The cec_get_edid_spa_location() function did not verify that the IEEE
identifier in the Vendor Specific Data Block matched the HDMI-LLC
identifier. This could result in the wrong VSDB block being returned.
For example, for HDMI 2.0 EDIDs there is also a HDMI Forum VSDB.
So check the IEEE identifier as well.

Most CEC adapters will still receive broadcast messages, even if no logical
addresses are claimed. But those messages should only be passed on for
monitoring purposes, but not for processing by either kernel or userspace
if userspace didn't call CEC_ADAP_S_LOG_ADDRS first.
So if adap->log_addrs.log_addr_mask is 0, then just return before passing
the received message on to the processing code.

Up to 4 logical addresses can be claimed. Make sure that any
unclaimed logical addresses are set to CEC_LOG_ADDR_INVALID as
per the documentation.
Take special care in the unregistered case: when falling back to
unregistered num_log_addrs may be > 1, so mark those as invalid.
