[PATCH 0/2] mtd: nandsim: fix error handling

[Sheng Yong]

These 2 patches fix error handling when nandsim initialization fails.

In alloc_device(), if creating slab memory fails, free_device() will try
to destroy the slab memory without checking if it exists.  PATCH 1 fixes
it.

If something goes wrong in init_nandsim(), it calls free_device() before
returning. However, the caller of init_nandsim() - ns_init_module() - also
does the cleanup by calling free_nandsim(). This causes double free. PATCH
2 fixes it.

Thanks,
Sheng
