Subject: [PATCH 5/6] nvmet: remove unnecessary function parameter
Date: Tue, 16 Feb 2021 13:31:11 -0800	[thread overview]
Message-ID: <20210216213112.20078-6-chaitanya.kulkarni@wdc.com> (raw)
In-Reply-To: <20210216213112.20078-1-chaitanya.kulkarni@wdc.com>

In nvmet_check_ctrl_status() cmd can be derived from nvmet_req. Remove
the local variable cmd in the nvmet_check_ctrl_status() and function
parameter cmd for nvmet_check_ctrl_status(). Derive the cmd value from
req parameter in the nvmet_check_ctrl_status().
