From eb2a6b800c2d1336cce6709d48c42753a611c07b Mon Sep 17 00:00:00 2001 From: Christophe Jaillet Date: Mon, 7 Aug 2017 00:00:17 +0200 Subject: qed: Fix a memory allocation failure test in 'qed_mcp_cmd_init()' We allocate 'p_info->mfw_mb_cur' and 'p_info->mfw_mb_shadow' but we check 'p_info->mfw_mb_addr' instead of 'p_info->mfw_mb_cur'. 'p_info->mfw_mb_addr' is never 0, because it is initiliazed a few lines above in 'qed_load_mcp_offsets()'. Update the test and check the result of the 2 'kzalloc()' instead.
