From: Michael Nosthoff committed@heine.so
commit 8b438686a001db64c21782d04ef68111e53c45d9 upstream.
Commit 7383d44b added a pointer pdata which get set to the default platform_data when non was defined in the device. But it did not pass this pointer to the st_sensors_init_sensor call but still used the maybe uninitialized platform_data from dev.
This breaks initialization when no platform_data is given and the optional st,drdy-int-pin devicetree option is not set.
This commit fixes this.
