This patch has been added to the 3.18 stable tree. If you have any
objections, please let us know.
===============
[ Upstream commit d43698e8abb58a6ac47d16e0f47bb55f452e4fc4 ]
Commit 2473238eac95 ("ihex: add support for CS:IP/EIP records") removes
the "default:" statement in the switch block, making the "return
usage();" line dead code and ihex2fw silently ignoring unknown options.
Restore this statement.
This bug was found by building with HOSTCC=clang and adding
-Wunreachable-code-return to HOSTCFLAGS.
Fixes: 2473238eac95 ("ihex: add support for CS:IP/EIP records")
