[PATCH OLK-5.10] media: go7007: fix a memleak in go7007_load_encoder

From: Zhipeng Lu <alexious(a)zju.edu.cn> stable inclusion from stable-v5.10.214 commit b49fe84c6cefcc1c2336d793b53442e716c95073 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9L9IB CVE: CVE-2024-27074 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit b9b683844b01d171a72b9c0419a2d760d946ee12 ] In go7007_load_encoder, bounce(i.e. go->boot_fw), is allocated without a deallocation thereafter. After the following call chain: saa7134_go7007_init |-> go7007_boot_encoder |-> go7007_load_encoder |-> kfree(go) go is freed and thus bounce is leaked.
