From cc7447a5fa92759b0856d6a83ba2539c6a94e67e Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Wed, 16 Jun 2010 11:44:18 +0200 Subject: Driver core: Drop __must_check from bus_for_each_drv() There is little rationale for marking bus_for_each_drv() __must_check. It is more of an iteration helper than a real function. You don't know in advance which callback it will be used on, so you have no clue how important it can be to check the returned value. In practice, this helper function can be used for best-effort tasks. As a matter of fact, bus_for_each_dev() is not marked __must_check. So remove it from bus_for_each_drv() as well. This is the same that was done back in October 2006 by Russell King for device_for_each_child(), for exactly the same reasons.
