Date: Fri, 9 Mar 2007 19:34:19 +0900 From: Tejun Heo <htejun@...il.com> To: gregkh@...e.de, Jeff Garzik <jeff@...zik.org>, linux-kernel@...r.kernel.org, linux-ide@...r.kernel.org Subject: [PATCH] devres: release resources on device_del() Some platform devices are driven without driver attached, so managed resources can be acquired without driver attached. Make sure such resources are released by calling devres_release_all() in device_del(). Signed-off-by: Tejun Heo <htejun@...il.com> --- This one fixes oops on pata_platform and pata_legacy unload. libata being the only user of devres at the moment. I think this can go through libata-dev#upstream. drivers/base/core.c | 7 +++++++ 1 files changed, 7 insertions(+), 0 deletions(-) diff --git a/drivers/base/core.c b/drivers/base/core.c index cf2a398..89ebe36 100644 --- a/drivers/base/core.c +++ b/drivers/base/core.c @@ -787,6 +787,13 @@ void device_del(struct device * dev) device_remove_attrs(dev); bus_remove_device(dev); + /* + * Some platform devices are driven without driver attached + * and managed resources may have been acquired.
