From mboxrd@z Thu Jan 1 00:00:00 1970 From: Phil Reid Subject: [PATCH v2 2/4] power: sbs-battery: Request threaded irq and fix dev callback cookie Date: Mon, 25 Jul 2016 10:42:58 +0800 Message-ID: <1469414580-14121-3-git-send-email-preid@electromag.com.au> References: <1469414580-14121-1-git-send-email-preid@electromag.com.au> Return-path: Received: from 203-59-230-133.perm.iinet.net.au ([203.59.230.133]:48258 "EHLO preid-centos7.electromag.com.au" rhost-flags-OK-OK-OK-FAIL) by vger.kernel.org with ESMTP id S1752582AbcGYCnJ (ORCPT ); Sun, 24 Jul 2016 22:43:09 -0400 In-Reply-To: <1469414580-14121-1-git-send-email-preid@electromag.com.au> Sender: linux-pm-owner@vger.kernel.org List-Id: linux-pm@vger.kernel.org To: sre@kernel.org, dbaryshkov@gmail.com, dwmw2@infradead.org, linux-pm@vger.kernel.org Cc: Phil Reid Currently the battery detect gpio can not be used with a chained interrupt controller that requires threaded irq handlers. Use threaded irq instead. In addition this was not going to be working at present because chip->power_supply is assigned after the request irq call.
