Subject: [PATCH 6/8] mfd: stmpe: Constify static struct resource
Date: Tue, 22 Sep 2020 21:26:57 +0200 [thread overview]
Message-ID: <20200922192659.14535-7-rikard.falkeborn@gmail.com> (raw)
In-Reply-To: <20200922192659.14535-1-rikard.falkeborn@gmail.com>
Constify a couple of static struct resource. The only usage of the
structs is 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.
