[PATCH 2/3] IIO: st_sensors_i2c.c: Don't print error on failed ACPI match

[Nikolaus Voss]

If there is a ACPI node for a i2c device but HID/CID doesn't match, there
could still be a ACPI_DT_NAMESPACE_HID / PRP0001 HID entry which is
matched against the i2c device ID table, so don't print an error
message.
