From 66be392a48f9d5256b4ba582ff06303fe97b5ca2 Mon Sep 17 00:00:00 2001 From: Alexandru Ardelean Date: Thu, 27 Feb 2020 15:52:22 +0200 Subject: [PATCH] iio: core: drop devm_iio_device_free() API call It's unused so far, so it can be removed. Also makes sense to remove it to discourage weird uses of this call during review. This is the last user of 'devm_iio_device_match()', so it can be removed as well in this patch.
