Subject: helper/command: remove unused functions and make static local ones
X-Git-Tag: v0.11.0-rc1~263
X-Git-Url: https://review.openocd.org/gitweb?p=openocd.git;a=commitdiff_plain;h=d8ac0086f957fabf63d596a3b8d396b110bc696d

helper/command: remove unused functions and make static local ones

The function command_find_in_parent() is never used in OpenOCD, so
remove it.

The functions command_name() and [un]register_command() are only
used internally in command.c, so make them static.
