Subject: [PATCH AUTOSEL 6.3 12/19] nfcsim.c: Fix error checking for debugfs_create_dir

From: Osama Muhammad <osmtendev@...il.com>

[ Upstream commit 9b9e46aa07273ceb96866b2e812b46f1ee0b8d2f ]

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.
