From 294c34e704e78d641b039064ce72d4531afe0088 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Thu, 26 Aug 2021 13:53:24 +0300 Subject: [PATCH] media: ipu3-cio2: Drop reference on error path in cio2_bridge_connect_sensor() The commit 71f642833284 ("ACPI: utils: Fix reference counting in for_each_acpi_dev_match()") moved adev assignment outside of error path and hence made acpi_dev_put(sensor->adev) a no-op. We still need to drop reference count on error path, and to achieve that, replace sensor->adev by locally assigned adev. Fixes: 71f642833284 ("ACPI: utils: Fix reference counting in for_each_acpi_dev_match()") Depends-on: fc68f42aa737 ("ACPI: fix NULL pointer dereference") Reported-by: Jens Axboe Signed-off-by: Andy Shevchenko Acked-by: Sakari Ailus Signed-off-by: Rafael J.
