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

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


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.
