From 2289adbfa559050d2a38bcd9caac1c18b800e928 Mon Sep 17 00:00:00 2001 From: Navid Emamdoost Date: Wed, 9 Oct 2019 12:01:47 -0300 Subject: [PATCH] media: usb: fix memory leak in af9005_identify_state In af9005_identify_state when returning -EIO the allocated buffer should be released. Replace the "return -EIO" with assignment into ret and move deb_info() under a check.
