From e18945b159a1cdbc031f1d3b0b7e515a33bdcbf7 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Fri, 27 Sep 2013 21:47:21 -0700 Subject: driver-core: remove struct bus_type.drv_attrs Now that all in-kernel users of bus_type.drv_attrs have been converted to use drv_groups instead, the drv_attrs field, and logic surrounding it, can be removed.
