set_device_description is oopsing with a null pointer at boot for me on
2.5.26-rmk1 with ohci-hcd on sa-1111. The problem apparently is the new
code that computes a clever name for the device -- a "return" statement
after the first sprintf() gets around the problem. If the problem isn't
obvious to whomever recently changed this code, I'll track it down when
I have some more time.
Cheers,

ksymoops 2.4.5 on i686 2.4.19-pre3-ac2-friction1. Options used
-v ./vmlinux (default)
-K (default)
-L (default)
-o ./_modules_ (default)
-m ./System.map (default)
Warning: You did not tell me where to find symbol information. I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.
No modules in ksyms, skipping objects
