From 6b50d038e7c668eb60b18c2fba8982a22e36527e Mon Sep 17 00:00:00 2001 From: Andrew Ruder Date: Wed, 4 Jun 2014 17:28:44 -0500 Subject: [PATCH] dm9000: acquire irq flags from device tree The DM9000 supports both active high interrupts and active low interrupts. This is configured via the attached EEPROM. In the device-tree case, make sure that the DM9000 driver passes the correct flags to request_irq. Signed-off-by: Andrew Ruder Signed-off-by: David S.
