Subject: [PATCH 1/1] USB: usblcd, fix memory leak
Date: Wed, 23 Sep 2009 16:09:56 +0200 [thread overview]
Message-ID: <1253714996-6495-1-git-send-email-jirislaby@gmail.com> (raw)
Stanse found a memory leak in lcd_probe. Instead of returning without
releasing the memory, jump to the error label which frees it.
