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 <axboe@kernel.dk> Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Acked-by: Sakari Ailus <sakari.ailus@linux.intel.com> Signed-off-by: Rafael J.
