From 33ac1257ff0dee2e9c7f009b1c1914b7990217b2 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Fri, 10 Jan 2014 08:57:31 -0500 Subject: sysfs, driver-core: remove unused {sysfs|device}_schedule_callback_owner() All device_schedule_callback_owner() users are converted to use device_remove_file_self(). Remove now unused {sysfs|device}_schedule_callback_owner().

So we avoid maintaining a possibly unused `cpu' variable, to avoid the following compilation warning: drivers/base/topology.c: In function ‘show_physical_package_id’: drivers/base/topology.c:103:118: warning: unused variable ‘cpu’ [-Wunused-variable] define_id_show_func(physical_package_id); drivers/base/topology.c: In function ‘show_core_id’: drivers/base/topology.c:106:106: warning: unused variable ‘cpu’ [-Wunused-variable] define_id_show_func(core_id); This can be seen with e.g. x86 defconfig and CONFIG_SMP not set.
