Hi!
[ 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.
I don't think this is good idea; user will wonder why he can't see debugfs files, and pr_err() is quite suitable way to handle this.
Anyway, this does not really fix a bug, so we should not be putting it into stable.
Best regards, Pavel
