From 6c2d4dd139de417d18151b98c157aa35387038a3 Mon Sep 17 00:00:00 2001 From: Guennadi Liakhovetski Date: Thu, 12 Aug 2010 17:16:00 -0300 Subject: V4L/DVB: V4L2: avoid name conflicts in macros "sd" and "err" are too common names to be used in macros for local variables. Prefix them with an underscore to avoid name clashing.

The sub-devices without a listed module name don't result in and I2C sub-device being created, as they either are IR devices or don't have an I2C address listed. It's thus safe to rely on modaliases only. All corresponding I2C modules have been checked, and all of them include a module aliases table with names corresponding to what the ivtv driver uses.
