[PATCH 1/5] platform/x86/intel/ifs: Call release_firmware() when handling errors.

From: Ashok Raj
Date: Thu Jan 25 2024 - 03:23:46 EST


From: Jithu Joseph <jithu.joseph@xxxxxxxxx>

Missing release_firmware() due to error handling blocked any future image
loading.

Fix the return code and release_fiwmare() to release the bad image.
