From 19c38de88a80913351fcacefdb461cc0b585fa87 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Wed, 12 Sep 2007 15:06:57 -0700 Subject: [PATCH] kobjects: fix up improper use of the kobject name field A number of different drivers incorrect access the kobject name field directly. This is not correct as the name might not be in the array. Use the proper accessor function instead. --- block/elevator.c | 2 +- block/ll_rw_blk.c | 2 +- drivers/acpi/bus.c | 2 +- drivers/cpufreq/cpufreq.c | 2 +- drivers/md/md.c | 3 +-- drivers/net/ibmveth.c | 2 +- drivers/pci/setup-irq.c | 2 +- fs/partitions/check.c | 12 +++++++----- fs/sysfs/dir.c | 2 +- net/bridge/br_sysfs_br.c | 2 +- 10 files changed, 16 insertions(+), 15 deletions(-) diff --git a/block/elevator.c b/block/elevator.c index c6d153de9fd..b9c518afe1f 100644 --- a/block/elevator.c +++ b/block/elevator.c @@ -186,7 +186,7 @@ static elevator_t *elevator_alloc(struct request_queue *q, eq->ops = &e->ops;
