[ Upstream commit 106101303eda8f93c65158e5d72b2cc6088ed034 ]
softsynth_probe misses a call misc_deregister() in an error path, this
patch fixes that.
This seems incorrect. Registration failed, we can't really deregister.
I checked random other caller of misc_register(), and it does not seem
this API is unusual.
