[PATCH] gspca: make sd_desc const

[PATCH] gspca: make sd_desc const

[Németh Márton]

From: Márton Németh <nm127@freemail.hu>

The function callbacks in sd_desc are defined at compile time and
they do not change at runtime. Make the sd_desc initializations const.

The semantic match that finds this kind of pattern is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>

	static const struct sd_desc x = ...;
@depends on !c@
identifier x;
@@
	static
+	const
	struct sd_desc x = ...;
// </smpl>
