[PATCH 0/7] iio: validate SPI match data before use

[Jiale Yao]

SPI driver_override can bind a device without a matching entry in the
driver's ID tables.  spi_get_device_match_data() then returns NULL.

These seven IIO drivers use that result without checking it, causing a
NULL pointer dereference during probe.  Add the missing checks before
the match data is used.
