NFC: NCI: nci_spi_recv_frame() now returns (not forward) the read frame
Previously, nci_spi_recv_frame() would directly transmit incoming frames to the NCI Core. However, it turns out that some NFC NCI Chips will add additional proprietary headers that must be handled/removed before NCI Core gets a chance to handle the frame. With this modification, the chip phy or driver are now responsible to transmit incoming frames to NCI Core after proper treatment, and NCI SPI becomes a driver helper instead of sitting between the NFC driver and NCI Core. As a general rule in NFC, *_recv_frame() APIs are used to deliver an incoming frame to an upper layer. To better suit the actual purpose of nci_spi_recv_frame(), and go along with its nci_spi_send() counterpart, the function is renamed to nci_spi_read() The skb is returned as the function result Signed-off-by: Eric Lapuyade <eric.lapuyade@intel.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
