Subject[PATCH net] nfc: nci: Fix handling of zero-length payload packets in nci_rx_work()
Date
When nci_rx_work() receives a zero-length payload packet, it should
discard the packet without exiting the loop. Instead, it should continue
processing subsequent packets.

Fixes: d24b03535e5e ("nfc: nci: Fix uninit-value in nci_dev_up and nci_ntf_packet")
Closes: https://lore.kernel.org/lkml/20240428134525.GW516117@kernel.org/T/
