From 858322c409e0aba8f70810d23f35c482744f007c Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Wed, 14 Jun 2023 16:06:47 +0300 Subject: [PATCH] media: mediatek: vcodec: fix resource leaks in vdec_msg_queue_init() [ Upstream commit cf10b0bb503c974ba049d6f888b21178be20a962 ] If we encounter any error in the vdec_msg_queue_init() then we need to set "msg_queue->wdma_addr.size = 0;". Normally, this is done inside the vdec_msg_queue_deinit() function. However, if the first call to allocate &msg_queue->wdma_addr fails, then the vdec_msg_queue_deinit() function is a no-op. For that situation, just set the size to zero explicitly and return. There were two other error paths which did not clean up before returning. Change those error paths to goto mem_alloc_err.
