NFC: nfcmrvl: double free on error path
The nci_spi_send() function calls kfree_skb(skb) on both error and success so this extra kfree_skb() is a double free. Fixes: caf6e49bf6d0 ("NFC: nfcmrvl: add spi driver") Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
