Subject: [PATCH v4 02/47] soc: fsl: qe: drop volatile qualifier of struct qe_ic::regs
Date:   Fri,  8 Nov 2019 14:00:38 +0100
Message-Id: <20191108130123.6839-3-linux@rasmusvillemoes.dk>
In-Reply-To: <20191108130123.6839-1-linux@rasmusvillemoes.dk>

Precedence: bulk

The actual io accessors (e.g. in_be32) implicitly add a volatile
qualifier to their address argument. Remove volatile from the struct
definition and the qe_ic_(read/write) helpers, in preparation for
switching from the ppc-specific io accessors to generic ones.
