[PATCH] mailbox: mailbox-xgene-slimpro: constify mbox_chan_ops structure

From: Bhumika Goyal
Date: Sat Jan 21 2017 - 11:56:07 EST


Declare mbox_chan_ops structure as const as it is only stored in the ops
field of a mbox_controller structure. This field is of type const, so
add const to structure declaration of mbox_chan_ops structure.
