iio: ak8975: fix maybe-uninitialized warning
[ Upstream commit 05be8d4101d960bad271d32b4f6096af1ccb1534 ]
If i2c_device_id *id is NULL and acpi_match_device returns NULL too,
then chipset may be unitialized when accessing &ak_def_array[chipset] in
ak8975_probe. Therefore initialize chipset to AK_MAX_TYPE, which will
return an error when not changed.
This patch fixes the following maybe-uninitialized warning:
drivers/iio/magnetometer/ak8975.c: In function ‘ak8975_probe’:
drivers/iio/magnetometer/ak8975.c:788:14: warning: ‘chipset’ may be used
uninitialized in this function [-Wmaybe-uninitialized]
data->def = &ak_def_array[chipset];
