From 881763361e8283a6d33d5a30ac6edc36e7dc6d44 Mon Sep 17 00:00:00 2001 From: Jesper Juhl Date: Sun, 29 Jan 2012 21:55:28 +0100 Subject: [PATCH] staging, media, easycap: Fix mem leak in easycap_usb_probe() If allocating 'pdata_urb' fails, the function will return -ENOMEM without freeing the memory allocated, just a few lines above, for 'purb' and will leak that memory when 'purb' goes out of scope. This patch resolves the leak by freeing the allocated storage with usb_free_urb() before the return.
