Bluetooth: hci_uart: Fix dereferencing of ERR_PTR
If h4_recv_buf() return ERR_PTR instead sk_buff pointer, it should be cleared once PTR_ERR is completed for the further dereference such as h4_recv(), or h4_close(). Signed-off-by: Chan-yeol Park <chanyeol.park@samsung.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
