Subject: [PATCH 3/4] mfd: intel-m10-bmc: Move m10bmc_sys_read() away from header
Date:   Wed,  5 Apr 2023 11:01:51 +0300
Message-Id: <20230405080152.6732-4-ilpo.jarvinen@linux.intel.com>
In-Reply-To: <20230405080152.6732-1-ilpo.jarvinen@linux.intel.com>
References: <20230405080152.6732-1-ilpo.jarvinen@linux.intel.com>
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Precedence: bulk

Move m10bmc_sys_read() out from the header to prepare it for adding
more code into the function which would make it too large to be a
static inline any more.

While at it, replace the vague wording in function comment with more
precise statements.
