From e51cc6b3a365e170d3ebe51c2308fdd42e027a46 Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Thu, 11 Aug 2005 23:36:49 +0200 Subject: [PATCH] [PATCH] I2C: Kill i2c_algorithm.id (2/7) Use the adapter id rather than the algorithm id to detect the i2c-isa pseudo-adapter. This saves one level of dereferencing, and the algorithm ids will soon be gone anyway.
