regmap_update_bits could fail and deserves a check.
The patch adds the checks and if it fails, returns its error
code upstream.

pull-request: ieee802154-next 2018-10-04
An update from ieee802154 for *net-next*
A very quite cycle in the ieee802154 subsystem. We only have two cleanup
patches for this pull request.
Xue removed the platform_data struct handling from the mcr20a driver and
Alexander cleaned up some left overs in the hwsim driver.
Please pull, or let me know if there are any problems.

The struct mcr20a_platform_data is uesed only in probe function
and it holds only one member. So it is not necessary to reserve it.
Using gpiod family API to handle reset pin.

The combination of defined constants are used to present the
state of IRQ so the magic numbers has been replaced.
This is a simple coding style change which should have no impact on
runtime code execution.

Without CONFIG_GPIOLIB, some headers are not included implicitly,
leading to a build failure:
drivers/net/ieee802154/mcr20a.c: In function 'mcr20a_probe':
drivers/net/ieee802154/mcr20a.c:1347:13: error: implicit declaration of function 'irq_get_trigger_type'; did you mean 'irq_get_irqchip_state'? [-Werror=implicit-function-declaration]
This includes gpio/consumer.h and irq.h directly rather through the
gpiolib header.

We already allocated the device and platform data at this
point. Instead of simply return from the probe function we
need to cleanup the resources first.

Variable 'val' is not being initialized and is later being logically
or'd with DAR_PHY_CTRL4_PROMISCUOUS. Considering this variable is never
being read anyway we may as well remove val altogether.

The MCR20AVHM transceiver (or MCR20A) is a low power,
high-performance 2.4 GHz, IEEE 802.15.4 compliant transceiver.
This driver implements a subset of ieee802154_ops.
It has no support for CSMA due to lack of hardware support.
It has currently no support for its proprietary Dual-PAN feature.
