#1228483 — [PATCH 3.14 26/29] of/address: Dont loop forever in of_find_matching_node_by_address().

3.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: David Daney <david.daney@cavium.com>

commit 3a496b00b6f90c41bd21a410871dfc97d4f3c7ab upstream.

If the internal call to of_address_to_resource() fails, we end up
looping forever in of_find_matching_node_by_address().  This can be
caused by a defective device tree, or calling with an incorrect
matches argument.

Fix by calling of_find_matching_node() unconditionally at the end of
the loop.

#1228487 — [PATCH 3.14 27/29] ARM: OMAP2+: DRA7: clockdomain: change l4per2_7xx_clkdm to SW_WKUP

3.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Vignesh R <vigneshr@ti.com>

commit b9e23f321940d2db2c9def8ff723b8464fb86343 upstream.

Legacy IPs like PWMSS, present under l4per2_7xx_clkdm, cannot support
smart-idle when its clock domain is in HW_AUTO on DRA7 SoCs. Hence,
program clock domain to SW_WKUP.

#1228488 — [PATCH 3.14 28/29] drivercore: Fix unregistration path of platform devices

3.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Grant Likely <grant.likely@linaro.org>

commit 7f5dcaf1fdf289767a126a0a5cc3ef39b5254b06 upstream.

The unregister path of platform_device is broken. On registration, it
will register all resources with either a parent already set, or
type==IORESOURCE_{IO,MEM}. However, on unregister it will release
everything with type==IORESOURCE_{IO,MEM}, but ignore the others. There
are also cases where resources don't get registered in the first place,
like with devices created by of_platform_populate()*.

Fix the unregister path to be symmetrical with the register path by
checking the parent pointer instead of the type field to decide which
resources to unregister. This is safe because the upshot of the
registration path algorithm is that registered resources have a parent
pointer, and non-registered resources do not.

* It can be argued that of_platform_populate() should be registering
  it's resources, and they argument has some merit. However, there are
  quite a few platforms that end up broken if we try to do that due to
  overlapping resources in the device tree. Until that is fixed, we need
  to solve the immediate problem.

#1228493 — [PATCH 3.14 16/29] serial: 8250: dont bind to SMSC IrCC IR port

3.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: "Maciej S. Szmigiero" <mail@maciej.szmigiero.name>

commit ffa34de03bcfbfa88d8352942bc238bb48e94e2d upstream.

SMSC IrCC SIR/FIR port should not be bound to by
(legacy) serial driver so its own driver (smsc-ircc2)
can bind to it.

3.14-stable review patch.  If anyone has any objections, please let me know.

From: Andrey Ryabinin <aryabinin@odin.com>

commit 71c6da846be478a61556717ef1ee1cea91f5d6a8 upstream.

Currently context size (cra_ctxsize) doesn't specified for
ghash_async_alg. Which means it's zero. Thus crypto_create_tfm()
doesn't allocate needed space for ghash_async_ctx, so any
read/write to ctx (e.g. in ghash_async_init_tfm()) is not valid.

in a NULL pointer being returned (and subsequently used). I did not go deeper

#1228707 — [PATCH 3.14 07/29] iio: Add inverse unit conversion macros

3.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Lars-Peter Clausen <lars@metafoo.de>

commit c689a923c867eac40ed3826c1d9328edea8b6bc7 upstream.

Add inverse unit conversion macro to convert from standard IIO units to
units that might be used by some devices.

Those are useful in combination with scale factors that are specified as
IIO_VAL_FRACTIONAL. Typically the denominator for those specifications will
contain the maximum raw value the sensor will generate and the numerator
the value it maps to in a specific unit. Sometimes datasheets specify those
in different units than the standard IIO units (e.g. degree/s instead of
rad/s) and so we need to do a unit conversion.

>From a mathematical point of view it does not make a difference whether we
apply the unit conversion to the numerator or the inverse unit conversion
to the denominator since (x / y) / z = x / (y * z). But as the denominator
is typically a larger value and we are rounding both the numerator and
denominator to integer values using the later method gives us a better
precision (E.g. the relative error is smaller if we round 8000.3 to 8000
rather than rounding 8.3 to 8).

This is where in inverse unit conversion macros will be used.

Marked for stable as used by some upcoming fixes.

#1228711 — [PATCH 3.14 21/29] xtensa: fix kernel register spilling

3.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Max Filippov <jcmvbkbc@gmail.com>

commit 77d6273e79e3a86552fcf10cdd31a69b46ed2ce6 upstream.

call12 can't be safely used as the first call in the inline function,
because the compiler does not extend the stack frame of the bounding
function accordingly, which may result in corruption of local variables.

If a call needs to be done, do call8 first followed by call12.

For pure assembly code in _switch_to increase stack frame size of the
bounding function.

#1228713 — [PATCH 3.14 15/29] usb: host: ehci-sys: delete useless bus_to_hcd conversion

3.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Peter Chen <peter.chen@freescale.com>

commit 0521cfd06e1ebcd575e7ae36aab068b38df23850 upstream.

The ehci platform device's drvdata is the pointer of struct usb_hcd
already, so we doesn't need to call bus_to_hcd conversion again.

#1228715 — [PATCH 3.14 09/29] staging: comedi: adl_pci7x3x: fix digital output on PCI-7230

3.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ian Abbott <abbotti@mev.co.uk>

commit ad83dbd974feb2e2a8cc071a1d28782bd4d2c70e upstream.

The "adl_pci7x3x" driver replaced the "adl_pci7230" and "adl_pci7432"
drivers in commits 8f567c373c4b ("staging: comedi: new adl_pci7x3x
driver") and 657f77d173d3 ("staging: comedi: remove adl_pci7230 and
adl_pci7432 drivers").  Although the new driver code agrees with the
user manuals for the respective boards, digital outputs stopped working
on the PCI-7230.  This has 16 digital output channels and the previous
adl_pci7230 driver shifted the 16 bit output state left by 16 bits
before writing to the hardware register.  The new adl_pci7x3x driver
doesn't do that.  Fix it in `adl_pci7x3x_do_insn_bits()` by checking
for the special case of the subdevice having only 16 channels and
duplicating the 16 bit output state into both halves of the 32-bit
register.  That should work both for what the board actually does and
for what the user manual says it should do.
