omap: Fix arch/arm/mach-omap2/mux.c: Off by one error
David Binderman ran the sourceforge tool cppcheck over the source code of the new Linux kernel 2.6.33-rc6: [./arm/mach-omap2/mux.c:492]: (error) Buffer access out-of-bounds 13 characters + 1 digit + 1 zero byte is more than 14 characters. Also add a comment on mode0 name length in case new omaps start using longer names. Reported-by: David Binderman <dcb314@hotmail.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
