kernel 3.6.7: sysfs: cannot create duplicate filename warnings

From: Chris Clayton
Date: Wed Feb 06 2013 - 08:34:25 EST


Hi,

I've been investigating problem with my Hauppauge WinTV HVR-1400 TV card (an expresscard) [1], and I've come across warnings produced when I unload and then reload the cx23885 driver.

Attached is the output from dmesg that shows the card being detected (by the PCI express hotplug driver) when it is inserted, the drivers being loaded and unloaded and, finally, the driver being reloaded and producing the warnings.

I get the same warning with 3.8.0-rc6+ (freshly pulled this morning).

I've searched Google and find thousands of hits going back over two years, but none of the first 20 pages of hits provided a solution.

Please let me know if I can provide any additional diagnostics, but cc me on any reply as I'm not subscribed.

Chris
