From 55dba52458a11126ff4445b5b94ebde03afcf47a Mon Sep 17 00:00:00 2001 From: Jiri Kosina Date: Fri, 26 Jun 2009 10:50:12 +0200 Subject: [PATCH] HID: fix memory leak on error path in debug code If hid_get_report() fails, we forgot to free the already allocated buffer for debugging messages on error path. Fix that up.
