platform/x86: i2c-multi-instantiate: Derive the device name from parent
commit 24a8d78a9affb63e5ced313ccde6888fe96edc6e upstream. When naming the new devices, instead of using the ACPI ID in the name as base, using the parent device's name. That makes it possible to support multiple multi-instance i2c devices of the same type in the same system. This fixes an issue seen on some Intel Kaby Lake based boards: sysfs: cannot create duplicate filename '/devices/pci0000:00/0000:00:15.0/i2c_designware.0/i2c-0/i2c-INT3515-tps6598x.0' Fixes: 2336dfadfb1e ("platform/x86: i2c-multi-instantiate: Allow to have same slaves") Cc: stable@vger.kernel.org Signed-off-by: Heikki Krogerus <heikki.krogerus@linux.intel.com> Reviewed-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
