Descriptions

In the Linux kernel, the following vulnerability has been resolved: nfc: nxp-nci: Fix potential memory leak in nxp_nci_send() nxp_nci_send() will call nxp_nci_i2c_write(), and only free skb when
nxp_nci_i2c_write() failed. However, even if the nxp_nci_i2c_write()
run succeeds, the skb will not be freed in nxp_nci_i2c_write(). As the
result, the skb will memleak. nxp_nci_send() should also free the skb
when nxp_nci_i2c_write() succeeds.
