From: Damien Le Moal <dlemoal@xxxxxxxxxx>
[ Upstream commit cd513e0434c3e736c549bc99bf7982658b25114d ]
When compiling with W=1, a warning result for the function
nvme_tcp_set_queue_io_cpu():
host/tcp.c:1578: warning: Function parameter or struct member 'queue'
not described in 'nvme_tcp_set_queue_io_cpu'
host/tcp.c:1578: warning: expecting prototype for Track the number of
queues assigned to each cpu using a global per(). Prototype was for
nvme_tcp_set_queue_io_cpu() instead
Avoid this warning by using the regular comment format for the function
nvme_tcp_set_queue_io_cpu() instead of the kdoc comment format.
