From 36010ff6788a058147ae15a1aebf97fd30fa51a9 Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Mon, 6 Oct 2008 12:22:51 +0200 Subject: [Bluetooth] Fix double frees on error paths of btusb and bpa10x drivers The transfer buffer of an URB will be automatically freed when using the URB_FREE_BUFFER transfer_flag. So the extra calls to kfree() will cause a double free.
