[PATCH] Staging: greybus: audio manager module: make char array const

[Ian Cowan]

Make the envp char array a const in the send_add_uevent function since
the value will never change. It will remain an array of the pointers to
the various char arrays.

There does exist a warning when running the checkpatch script to
make this a static variable, but there does not appear to be any advantage
to make this change.

Heh.  Don't send patches unless there is an advantage.

This patch breaks the build.  You need to at least try to compile your
changes before you send them.
