Subject: [PATCH 01/12] mfd: twl-core: don't depend on pdata->irq_base/end
Date: Fri, 2 Mar 2012 17:50:13 +0100	[thread overview]
Message-ID: <1330707024-23730-2-git-send-email-b-cousson@ti.com> (raw)
In-Reply-To: <1330707024-23730-1-git-send-email-b-cousson@ti.com>

From: Felipe Balbi <balbi@ti.com>

With sparse IRQs the driver shouldn't depend at all on
any IRQ values coming from board-file.

Remove every occurences of pdata->irq_base/end.
