Subject: [PATCH 2/8] mfd: intel: Constify static struct resource
Date:   Tue, 22 Sep 2020 21:26:53 +0200
Message-Id: <20200922192659.14535-3-rikard.falkeborn@gmail.com>

Constify a number of static struct resource. The only usage of the
structs are to assign their address to the resources field in the
mfd_cell struct. This allows the compiler to put them in read-only
memory. Done with the help of Coccinelle.
