platform/x86: int3472: Check for adev == NULL
[ Upstream commit cd2fd6eab480dfc247b737cf7a3d6b009c4d0f1c ]
Not all devices have an ACPI companion fwnode, so adev might be NULL. This
can e.g. (theoretically) happen when a user manually binds one of
the int3472 drivers to another i2c/platform device through sysfs.
Add a check for adev not being set and return -ENODEV in that case to
avoid a possible NULL pointer deref in skl_int3472_get_acpi_buffer().
