Subject: [PATCH 1/2] usb: gadget: uvc: constify vb2_ops structure
Date: Tue, 30 Oct 2018 16:31:21 +0100	[thread overview]
Message-ID: <1540913482-22130-2-git-send-email-Julia.Lawall@lip6.fr> (raw)
In-Reply-To: <1540913482-22130-1-git-send-email-Julia.Lawall@lip6.fr>

The vb2_ops structure can be const as it is only stored in the ops
field of a vb2_queue structure and this field is const.

Done with the help of Coccinelle.
