  iio: buffer: Fix memory leak in iio_buffers_alloc_sysfs_and_mask() (2021-10-21 10:26:38 +0100)

----------------------------------------------------------------
First set of IIO fixes for the 5.16 cycle

As these are very late in the 5.15 cycle and non are particularly urgent,
they can wait for the merge window.

Key element in this set is Yang Yingliang has identified a number of
issues in error paths introduced recently when we added multiple
buffer support.

Other fixes:
* adi,ad5662
  - Fix handling of i2c_master_send() return value.
* adi,ad5766
  - Fix a wrong dt-property name that indicated wrong units and
    did not mach the bindings.
  - Associated 'fix' of the bindings example to have a possible scale.
* st,pressure-spi
  - Add some missing entries to the spi_device_id table to ensure
    auto-loading works.
* ti,tsc2046
  - Fix a backwards comparison leading to a false dev_warn
