From 47b8b103f7f50d56568eb8d6cff0e3a2373f0eb3 Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Fri, 7 Oct 2005 23:56:46 +0200 Subject: [PATCH] [PATCH] i2c: Cleanup i2c-i801 ifdefs No more need to check for PEC support being available now that both the i2c-core and the i2c-i801 drivers are part of the Linux kernel source tree. It's just there.
