Hi all,

After merging the staging tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/iio/adc/ti-ads131e08.c: In function 'ads131e08_read_reg':
drivers/iio/adc/ti-ads131e08.c:180:5: error: 'struct spi_transfer' has no member named 'delay_usecs'
  180 |    .delay_usecs = st->sdecode_delay_us,
      |     ^~~~~~~~~~~
drivers/iio/adc/ti-ads131e08.c: In function 'ads131e08_write_reg':
drivers/iio/adc/ti-ads131e08.c:206:5: error: 'struct spi_transfer' has no member named 'delay_usecs'
  206 |    .delay_usecs = st->sdecode_delay_us,
      |     ^~~~~~~~~~~

Caused by commit

  d935eddd2799 ("iio: adc: Add driver for Texas Instruments ADS131E0x ADC family")

interacting with commit

  3ab1cce55337 ("spi: core: remove 'delay_usecs' field from spi_transfer")

from the spi tree.

I have applied the following merge fix patch.
