Subject[PATCH 3.19.y-ckt 015/146] firmware/ihex2fw.c: restore missing default in switch statement
Date
3.19.8-ckt2 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Nicolas Iooss <nicolas.iooss_linux@m4x.org>

commit d43698e8abb58a6ac47d16e0f47bb55f452e4fc4 upstream.

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")
