question about drivers/mailbox/pcc.c

[Julia Lawall]

Hello,

The patch 86c22f8c9a3b from Wed Nov 12 19:59:38 2014 in linux-next
introduces a file that contains two exported functions:
pcc_mbox_request_channel and pcc_mbox_free_channel.  As far as I can see,
these functions are not used by any modules in the kernel source tree.
Is there some code coming that will use them, or should they be removed?

thanks,
julia
