[PATCH 0/2] btsdio fixes on error path

[Tomas Winkler]

Please add btsdio fixes for error path to stable release.  Some sdio devices are not so stable so we are hitting this often and it leaves kernel in bad state.
Bluetooth: Fix TX error path in btsdio driver -  is needed for 2.6.27 and 2.6.28 kernel
btsdio: free sk_buff with kfree_skb  - is needed for 2.6.27 kernel
