From e420aed19a5f4a2715733f2a450e8958fa7e2638 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Wed, 13 May 2009 19:48:07 +0000 Subject: ir-kbd-i2c: Don't use i2c_client.name for our own needs From: Jean Delvare In the standard device driver binding model, the name field of struct i2c_client is used to match devices to their drivers, so we must stop using it for internal purposes. Define a separate field in struct IR_i2c as a replacement, and use it.

Ultimately it would be better if we could stop probing completely, but I suspect this won't be possible for all card types. There's certainly room for cleanups. For example, some drivers are sharing I2C adapter IDs, so they also had to share the list of I2C addresses being probed for an IR receiver. Now that each driver explicitly says which addresses should be probed, maybe some addresses can be dropped from some drivers. Also, the special cases in saa7134-i2c should probably be handled on a per-board basis. This would be more efficient and less risky than always probing extra addresses on all boards. I'll give it a try later.
