From e8c77bda05e5d93cce6f38cfdde4192307951dea Mon Sep 17 00:00:00 2001 From: Tobias Klauser Date: Wed, 18 Nov 2015 10:48:16 +0100 Subject: [PATCH] fpga manager: Fix firmware resource leak on error If fpga_mgr_buf_load() fails, the firmware resource previously allocated by request_firmware() is leaked. Fix it by calling release_firmware() regardless of the return value of fpga_mgr_buf_load(). Found by the Coverity scanner (CID 1339653).
