Subject: [PATCH 1/9] drivers/media/usb/airspy/airspy.c: drop unneeded goto

From: Julia Lawall <Julia.Lawall@...6.fr>

Delete jump to a label on the next line, when that label is not
used elsewhere.

A simplified version of the semantic patch that makes this change is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
@r@
identifier l;
@@

-if (...) goto l;
-l:
// </smpl>

Signed-off-by: Julia Lawall <Julia.Lawall@...6.fr>
