Subject: [PATCH v7 1/2] power: supply: twl4030-charger: move irq allocation to just before irqs are enabled
Date: Mon, 19 Jun 2017 10:41:45 +0200 [thread overview]
Message-ID: <2b919bea97f23c952e0141ed63d04dbbcea5c695.1497861705.git.hns@goldelico.com> (raw)
In-Reply-To: <cover.1497861705.git.hns@goldelico.com>
In-Reply-To: <cover.1497861705.git.hns@goldelico.com>
And initialize workers and notifiers as soon as possible.
This avoids a potential race if irqs are enabled and triggered too early
before the worker is properly set up.
