nfcsim.c: Fix error checking for debugfs_create_dir

osmten · davem330 · commit 9b9e46aa0727 · 2023-05-26T12:18:35.000+01:00
This patch fixes the error checking in nfcsim.c.
The DebugFS kernel API is developed in
a way that the caller can safely ignore the errors that
occur during the creation of DebugFS nodes.
