From 4ae2e594b70b04fb90fd5fef96a996f42ecea7d5 Mon Sep 17 00:00:00 2001 From: Jesper Juhl Date: Sat, 24 Mar 2012 18:39:18 -0300 Subject: [PATCH] [media] staging/media/as102: Don't call release_firmware() on uninitialized variable If, in drivers/staging/media/as102/as102_fw.c::as102_fw_upload(), the call cmd_buf = kzalloc(MAX_FW_PKT_SIZE, GFP_KERNEL); should fail and return NULL so that we jump to the 'error:' label, then we'll end up calling 'release_firmware(firmware);' with 'firmware' still uninitialized - not good. The easy fix is to just initialize 'firmware' to NULL when we declare it, since release_firmware() deals gracefully with being passed NULL pointers.
