Subject: iio: trigger: free trigger resource correctly
From: Alison Schofield <amsfield22(a)gmail.com>
[ Upstream commit 10e840dfb0b7fc345082dd9e5fff3c1c02e7690e ]
These stand-alone trigger drivers were using iio_trigger_put()
where they should have been using iio_trigger_free(). The
iio_trigger_put() adds a module_put which is bad since they
never did a module_get.
In the sysfs driver, module_get/put's are used as triggers are
added & removed. This extra module_put() occurs on an error path
in the probe routine (probably rare).
In the bfin-timer & interrupt trigger drivers, the module resources
are not explicitly managed, so it's doing a put on something that
was never get'd. It occurs on the probe error path and on the
remove path (not so rare).
Tested with the sysfs trigger driver.
The bfin & interrupt drivers were build tested & inspected only.

Subject: IB/ipoib: Change list_del to list_del_init in the tx object
From: Feras Daoud <ferasda(a)mellanox.com>
[ Upstream commit 27d41d29c7f093f6f77843624fbb080c1b4a8b9c ]
Since ipoib_cm_tx_start function and ipoib_cm_tx_reap function
belong to different work queues, they can run in parallel.
In this case if ipoib_cm_tx_reap calls list_del and release the
lock, ipoib_cm_tx_start may acquire it and call list_del_init
on the already deleted object.
Changing list_del to list_del_init in ipoib_cm_tx_reap fixes the problem.

The pinmux configuration in device tree was different from manual
muxing in <u-boot>/board/freescale/mx53loco/mx53loco.c
All pins were configured as NO_PAD_CTL(1 << 31), which was fine as the
bootloader already did the correct pinmuxing for us.
But recently u-boot is migrating to reuse device tree files from the
kernel tree, so it seems to be better to have the correct pinmuxing in
our files, too.

crypto_ahash_import() may be called either after

we always internally call init() as part of
import(), thus leaking memory and mappings if the
user has already called init() herself.
Fix this by only calling init() internally if the
state is not already initialized.

From: Juergen Gross <jgross(a)suse.com>
[ Upstream commit 56dd5af9bc23d0d5d23bb207c477715b4c2216c5 ]
The default for the maximum number of tx/rx queues of one interface is
the number of cpus of the system today. As each queue pair reserves 512
grant pages this default consumes a ridiculous number of grants for
large guests.
Limit the queue number to 8 as default. This value can be modified
via a module parameter if required.
