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
