From mboxrd@z Thu Jan 1 00:00:00 1970 From: Anton Vorontsov Subject: [PATCH 1/3] fsl_pq_mdio: Fix compiler/sparse warnings (part 1) Date: Thu, 5 Nov 2009 01:52:56 +0300 Message-ID: <20091104225256.GA29537@oksana.dev.rtsoft.ru> Mime-Version: 1.0 Content-Type: text/plain; charset=utf-8 Cc: Andy Fleming , Sandeep Gopalpet , netdev@vger.kernel.org, linuxppc-dev@ozlabs.org To: David Miller Return-path: Received: from imap.ru.mvista.com ([213.79.90.228]:11184 "EHLO buildserver.ru.mvista.com" rhost-flags-OK-FAIL-OK-FAIL) by vger.kernel.org with ESMTP id S932781AbZKDWww (ORCPT ); Wed, 4 Nov 2009 17:52:52 -0500 Content-Disposition: inline Sender: netdev-owner@vger.kernel.org List-ID: commit 1d2397d742b7a2b39b2f09dd9da3b9d1463f55e9 ("fsl_pq_mdio: Add Suport for etsec2.0 devices") introduced the following warnings: CHECK fsl_pq_mdio.c fsl_pq_mdio.c:287:22: warning: incorrect type in initializer (different base types) fsl_pq_mdio.c:287:22: expected unknown type 11 const *__mptr fsl_pq_mdio.c:287:22: got unsigned long long [unsigned] [assigned] [usertype] addr fsl_pq_mdio.c:287:19: warning: incorrect type in assignment (different base types) fsl_pq_mdio.c:287:19: expected unsigned long long [unsigned] [usertype] ioremap_miimcfg fsl_pq_mdio.c:287:19: got struct fsl_pq_mdio * CC fsl_pq_mdio.o fsl_pq_mdio.c: In function 'fsl_pq_mdio_probe': fsl_pq_mdio.c:287: warning: initialization makes pointer from integer without a cast fsl_pq_mdio.c:287: warning: assignment makes integer from pointer without a cast These warnings are not easy to fix without ugly __force casts. So, instead of introducing the casts, rework the code to substitute an offset from an already mapped area. This makes the code a lot simpler and less duplicated. Plus, from now on we don't actually map reserved registers on non-etsec2.0 devices, so we have more chances to catch programming errors.
