Comment (by tmatth):

 Replying to [comment:5 Cigaes]:
 > Your patch would clearly be right by itself, but the whole paragraph is
 just redundant:
 > [http://git.linuxtv.org/v4l-
 utils.git/blob/HEAD:/lib/libv4l2/libv4l2.c#l578]
 > {{{v4l2_open}}} already calls {{{v4l2_fd_open}}}, calling a second time
 only uses an additional slot in libv4l2 structures that will never be
 deallocated.
 > I sent a patch to the devel mailing list.

 Well spotted, it wasn't until I went through with gdb that I noticed
 v4l2_fd_open was getting called twice. Thanks for sending the patch.
