Subject: [PATCH] mtd: nandsim: remove debugfs entries in error path
Origin: https://git.kernel.org/linus/b974696da1cfc5aa0c29ed97dc8f6c239899e64b
The debugfs entries must be removed before an error is returned in the
probe function. Otherwise another try to load the module fails and when
the debugfs files are accessed without the module loaded, the kernel
still tries to call a function in that module.
Fixes: 5346c27c5fed ("mtd: nandsim: Introduce debugfs infrastructure")
