[PATCH] platform/mellanox: tmfifo: fix kernel-doc warnings

From: Randy Dunlap
Date: Tue Sep 26 2023 - 01:40:22 EST


Fix kernel-doc notation for structs and struct members to prevent
these warnings:

mlxbf-tmfifo.c:73: warning: cannot understand function prototype: 'struct mlxbf_tmfifo_vring '
mlxbf-tmfifo.c:128: warning: cannot understand function prototype: 'struct mlxbf_tmfifo_vdev '
mlxbf-tmfifo.c:146: warning: cannot understand function prototype: 'struct mlxbf_tmfifo_irq_info '
mlxbf-tmfifo.c:158: warning: cannot understand function prototype: 'struct mlxbf_tmfifo_io '
mlxbf-tmfifo.c:182: warning: cannot understand function prototype: 'struct mlxbf_tmfifo '
mlxbf-tmfifo.c:208: warning: cannot understand function prototype: 'struct mlxbf_tmfifo_msg_hdr '
mlxbf-tmfifo.c:138: warning: Function parameter or member 'config' not described in 'mlxbf_tmfifo_vdev'
mlxbf-tmfifo.c:212: warning: Function parameter or member 'unused' not described in 'mlxbf_tmfifo_msg_hdr'

Fixes: 1357dfd7261f ("platform/mellanox: Add TmFifo driver for Mellanox BlueField Soc")
Fixes: bc05ea63b394 ("platform/mellanox: Add BlueField-3 support in the tmfifo driver")
