98f97ba3e0 mfd: kempld-core: Fix callback return value check
commit c8648508eb upstream.

On success, callback function returns 0. So invert the if condition
check so that we can break out of loop.

6ed0f56de1 mfd: tc6393xb: Fail ohci suspend if full state restore is required
commit 1a5fb99de4 upstream.

Some boards with TC6393XB chip require full state restore during system
resume thanks to chip's VCC being cut off during suspend (Sharp SL-6000
tosa is one of them). Failing to do so would result in ohci Oops on
resume due to internal memory contentes being changed. Fail ohci suspend
on tc6393xb is full state restore is required.

Recommended workaround is to unbind tmio-ohci driver before suspend and
rebind it after resume.

b9b75d0775 mfd: rtsx_pcr: Fix MSI enable error handling
commit 5152970538 upstream.

pci_enable_msi() can return failure with both positive and negative
integers -- it returns 0 for success -- but is only tested here for
"if (ret < 0)".  This causes us to try to use MSI on the RTS5249 SD
reader in the Dell XPS 11 when enabling MSI failed, causing:

[    1.737110] rtsx_pci: probe of 0000:05:00.0 failed with error -110

d2501bb0cf mfd: ti_am335x_tscadc: Fix TSC resume
commit 6a71f38dd8 upstream.

In the resume path, the ADC invokes am335x_tsc_se_set_cache() with 0 as
the steps argument if continous mode is not in use. This in turn disables
all steps and so the TSC is not working until one ADC sampling is
performed.

This patch fixes it by writing the current cached mask instead of the
passed steps.

bb01842184 mfd: ti_am335x_tscadc: Fix TSC operation after ADC continouous mode
commit 6ac734d224 upstream.

After enabling and disabling ADC continuous mode via sysfs, ts_print_raw
fails to return any data. This is because when ADC is configured for
continuous mode, it disables touch screen steps.These steps are not
re-enabled when ADC continuous mode is disabled. Therefore existing values
of REG_SE needs to be cached before enabling continuous mode and
disabling touch screen steps and enabling ADC steps. The cached value
are to be restored to REG_SE once ADC is disabled.

eec08eecb8 mfd: omap-usb-host: Fix improper mask use.
commit 46de8ff8e8 upstream.

single-ulpi-bypass is a flag used for older OMAP3 silicon.

The flag when set, can excite code that improperly uses the
OMAP_UHH_HOSTCONFIG_UPLI_BYPASS define to clear the corresponding bit.
Instead it clears all of the other bits disabling all of the ports in
the process.

53135e6192 mfd: twl-core: Fix accessibility of some twl4030 audio registers
commit 56816b700c upstream.

There are some unused registers in twl4030 at I2C address 0x49 and function
twl4030_49_nop_reg() is used to check accessibility of that registers. These
registers are written in decimal format but the values are correct in
hexadecimal format. (It can be checked few lines above the patched code -
these registers are marked as unused there.)

As a consequence three registers of audio submodule are treated as
inaccessible (preamplifier carkit right and both handsfree registers).

00834e4d81 mfd: kempld-core: Fix potential hang-up during boot
commit 204747c970 upstream.

On PXT and COMe-cPC2 boards it is observed that the hardware
mutex is acquired but not being released during initialization.
This can result in a hang-up during boot if the driver is built
into the kernel.

Releasing the mutex twice if it was acquired fixes the problem.
Subsequent request/release cycles work as expected, so the fix is
only needed during initialization.

9ae64846e7 mfd: tps65910: Fix possible invalid pointer dereference on regmap_add_irq_chip fail
commit 483e2dfdbc upstream.

Fixes: 4aab3fadad ("mfd: tps65910: Move interrupt implementation code to mfd file")

tps65910_irq_init() sets 'tps65910->chip_irq' before calling
regmap_add_irq_chip(). If the regmap_add_irq_chip() call fails in
memory allocation of regmap_irq_chip_data members then:

1. The 'tps65910->chip_irq' will still hold some value
2. 'tps65910->irq_data' will be pointing to already freed memory
   (because regmap_add_irq_chip() will free it on error)

This results in invalid memory access during driver remove because the
tps65910_irq_exit() tests whether 'tps65910->chip_irq' is not zero.

commit 141050cf3d upstream.

During probe the driver allocates two dummy I2C devices for subchips in
function pm800_pages_init(). Additionally this function allocates
regmaps for these subchips. If any of these steps fail then these dummy
I2C devices are not freed and resources leak.

On pm800_pages_init() fail the driver must call pm800_pages_exit() to
unregister dummy I2C devices.

Currently the I2C device Ids conflict for the MFD and CODEC so
cannot be both instantiated on one platform. This patch updates
the Ids and names to make them unique from each other.

It should be noted that the I2C addresses for both PMIC and CODEC
are modifiable so instantiation of the two are kept as separate
devices, rather than instantiating the CODEC from the MFD code.

Pull regulator updates from Mark Brown:
 "A respin of the merges in the previous pull request with one extra
  fix.

  A quiet release for the regulator API, quite a large number of small
  improvements all over but other than the addition of new drivers for
  the AS3722 and MAX14577 there is nothing of substantial non-local
  impact"

The MUIC block in max77693 has different I2C address than PMIC. The
driver allocated two regmaps: for PMIC and MUIC. However it used the
same regmap_config (with max_register field) for both regmaps. Actual
maximum address of register for MUIC is different than for PMIC.

Define another regmap_config for MUIC with proper max_register value.

The regmap used by max77686 MFD driver was not freed with regmap_exit()
on driver exit. This lead to leak of resources.

Replace regmap_init_i2c() call in driver probe with initialization of
managed register map so the regmap will be properly freed by the device
