6.12-stable review patch. If anyone has any objections, please let me know.

From: Timur Tabi ttabi@nvidia.com
commit 66e82b6e0a28d4970383e1ee5d60f431001128cd upstream.
Function nvkm_gsp_fwsec_v2() sets 'ret' if the kmemdup() call fails, but it never uses or returns 'ret' after that point. We always need to release the firmware regardless, so do that and then check for error.
