  iio: adc: mcp3422: fix locking scope (2020-08-31 10:47:53 +0100)

----------------------------------------------------------------
First set of IIO fixes for the 5.9 cycle

Most of the fixes this time are for a long term issue that Lars-Peter
Clausen identified recently.

IIO assumes that any data pushed to the buffer interface (either kfifo
or another in kernel consumer) are naturally aligned.  Unfortunately
this isn't true in a number of drivers, mostly by failing to ensure
the buffer used is aligned suitably for an s64 timestamp.

For the ones covered this time we use a structure to enforce this
alignment, with the added need for __aligned(8) to ensure 8 byte
alignment of the timestamp on x86_32 and similar platforms where
it would be 4 byte aligned giving different padded from some other
architectures.

Patches to make this requirement clearer and potentially cause an
error print will follow once we've cleaned up existing cases.
Note that it is a very hard to hit problem and as a result of this
as we only have one bug report despite the problem being present
for many years.

Other fixes:
* cros_ec:
  - set gyroscope default frequency. For some older boards not having
    this set can lead to a choice that doesn't work.
* counter,microchip-tcb-capture:
  - Fix a wrong value check in error check.
* mcp3422
  - Fix locking to protect against race condition.
* meson-adc
  - Use right device when looking up fuse values for calibration.
* rockchip-adc
  - Fix missing Kconfig dependency.
* ti-ads1015:
  - Fix reading when CONFIG_PM not set.
