From 060d20d32ae7c6a20a8eac465795ed5bc9b37f7c Mon Sep 17 00:00:00 2001 From: =?utf8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Mon, 19 Oct 2009 22:19:28 +0200 Subject: [PATCH] imx/gpio: Use handle_level_irq MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit According to Russell King handle_edge_irq is only useful for "edge-based inputs where the controller does not remember transitions with the input masked." So using handle_edge_irq unconditionally for both edge and level irqs is wrong. Testing showed that the controller does remember transitions while the interrupt is masked. So use handle_level_irq unconditionally.
