Subject: [PATCH v2 2/4] null_blk: match the type of parameter nr_devices
Date: Fri, 13 Sep 2019 19:02:58 -0300
Message-ID: <20190913220300.422869-3-andrealmeid@collabora.com> (raw)
In-Reply-To: <20190913220300.422869-1-andrealmeid@collabora.com>

Since the variable nr_devices is an unsigned int, the module_param()
should also use this type. Change the type so they can match.

Signed-off-by: André Almeida <andrealmeid@collabora.com>
Fixes: f7c4ce890dd2 ("null_blk: validate the number of devices")
