From 9a3180e70e35ff69586ada5421b5e7bad52f60e4 Mon Sep 17 00:00:00 2001 From: David Brownell Date: Sun, 9 Sep 2007 22:29:13 +0200 Subject: i2c-gpio: Fix adapter number It turns out that platform_device.id is a "u32" so testing it for being nonnegative is useless when setting up an i2c bitbang device. Instead, do what the platform_bus code does and test it against the value "-1".
