Hi Janakarajan,

[auto build test WARNING on next-20170111]
[also build test WARNING on v4.10-rc3]
[cannot apply to tip/x86/core v4.9-rc8 v4.9-rc7 v4.9-rc6]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]

coccinelle warnings: (new ones prefixed by >>)

>> arch/x86/events/amd/uncore.c:365:2-7: WARNING: NULL check before freeing functions like kfree, debugfs_remove, debugfs_remove_recursive or usb_free_urb is not needed. Maybe consider reorganizing relevant code to avoid passing NULL values.

Please review and possibly fold the followup patch.
