ASoC: Intel: bytcht_es8316: fix HID handling
Same problem as with previous machine drivers, the codec dai uses a hard-coded name of "i2c-ESSX8316:00" but ACPI provides "i2c-ESSX8316:01" in some systems. Fix by overriding the hard-coded value with the codec name derived from the HID information Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=189261 Signed-off-by: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com> Reviewed-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Acked-By: Vinod Koul <vinod.koul@intel.com> Signed-off-by: Mark Brown <broonie@kernel.org>
