From 11d579ee0a19052a5a90ebfe0c39e7ed8ce8a9dc Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Sat, 28 Jun 2008 20:31:52 +0200 Subject: powerpc/mpc5200: Fix wrong 'no interrupt' handling in of_i2c If an I2C device node does not specify an interrupt, the .irq member of the board_info struct was set to -1. This caused crashes on following irq_dispose_mappings. Leave it NO_IRQ as returned from irq_of_parse_and_map. (Suggesting -1 as 'i2c-no-irq' used to be a bug in linux/i2c.h.)
