Re: [PATCH] cxl: Fix kobject memleak

Currently the error return path from kobject_init_and_add() is not
followed by a call to kobject_put() - which means we are leaking
the kobject.

Fix it by adding a call to kobject_put() in the error path of
kobject_init_and_add().

Thanks for the fix!

I note that the err1 label returns without calling kfree(cr) and I can't 
see a reason why we do that - so perhaps we should remove the return 
statement in err1: so it falls through?
