Subject: [PATCH] iio: adis16480: select CONFIG_CRC32
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

commit d9b540ee461cca7edca0dd2c2a42625c6b9ffb8f upstream.

In rare randconfig builds, the missing CRC32 helper causes
a link error:

ld.lld: error: undefined symbol: crc32_le
>>> referenced by usercopy_64.c
>>>               vmlinux.o:(adis16480_trigger_handler)
