This is file is generated by utils/keytable/gen_keytables.pl, so there is no
use in patching it.
Actually I think a better solution would be to be less pernickety about how
the protocol is specified. ir-ctl also does this. How about the following
patch.

Subject: [PATCH] [PATCH v4l-utils] ir-keytable: be more permissive on protocol
name
Allowed the protocol to be specified with or without underscores or
dashes. This also solves the problem of not being able to load
the streamzap keymap.
./ir-keytable -w rc_keymaps/streamzap
Protocol RC5_SZ invalid
