From 6026af6a53dffb50db87ef264294dff57ed3a845 Mon Sep 17 00:00:00 2001 From: Alexandru Ardelean Date: Wed, 16 Sep 2020 11:31:28 +0300 Subject: [PATCH] iio: adc: ad9467: refine mismatch vs unknown chip-id messages We should probably print what the expected chip-ID is. We already have that information available, based on the device specified via device-tree.
