## Description

In the Linux kernel, the following vulnerability has been resolved:  iio: imu: adis: Fix NULL pointer dereference in adis_init  The adis_init() function dereferences adis->ops to check if the individual function pointers (write, read, reset) are NULL, but does not first check if adis->ops itself is NULL.  Drivers like adis16480, adis16490, adis16545 and others do not set custom ops and rely on adis_init() assigning the defaults. Since struct adis is zero-initialized by devm_iio_device_alloc(), adis->ops is NULL when adis_init() is called, causing a NULL pointer dereference:      Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000     pc : adis_init+0xc0/0x118     Call trace:      adis_init+0xc0/0x118      adis16480_probe+0xe0/0x670  Fix this by checking if adis->ops is NULL before dereferencing it, falling through to assign the default ops in that case.
