Subject: [PATCH 0/4] gpu/drm: fix memory leak when radeon_driver_load_kms fails
Date: Fri, 31 Jul 2009 16:55:54 +0800	[thread overview]
Message-ID: <1249030558-24143-1-git-send-email-dfeng@redhat.com> (raw)

I've noticed a bundle of kmemleak reports on drm. When I look into dmesg,
I found: "[drm:radeon_driver_load_kms] *ERROR* Failed to initialize radeon,
disabling IOCTL". 

In radeon_driver_load_kms, if radeon_device_init fails, rdev is not freed.
Then radeon_driver_load_kms as dev->driver->load, if load fails in
drm_get_dev, memories allocated in drm_fill_in_dev will not be freed.

This patchset fixes those memory leaks, after this patchset applied, I didn't
see those drm kmemleak report.
