Subject: media: ipu-bridge: Add missing acpi_dev_put() in
ipu_bridge_get_ivsc_acpi_dev()
Author: Geert Uytterhoeven <geert+rene...@glider.be>
Date: Fri Sep 29 11:31:33 2023 +0200
In ipu_bridge_get_ivsc_acpi_dev(), the "ivsc_adev" acpi_device pointer
from the outer loop is handed over to the caller, which takes proper
care of its reference count.
However, the "consumer" acpi_device pointer from the inner loop is lost,
without decrementing its reference count.
Fix this by adding the missing call to acpi_dev_put().

driver")
