[RFC/commit 3/3] Delete unused variable in lynx_resume

[Joel Brobecker <brobecker at adacore dot com>]

Hello,

This patch eliminates a local variable that we never use.
It is an RFC, because I couldn't determine whether there was
something we were expected to do if the ptrace request failed
- which has never happened to us so far, AFAICT.

gdb/gdbserver/ChangeLog:

        * lynx-low.c (lynx_resume): Delete variable ret.

Tested on ppc-lynx5. OK to commit, or is there some error handling
protocol?

Thanks,
-- 
Joel
