[PATCH] adm1266.c: Drop error checking for debugfs_create_dir

[PATCH] adm1266.c: Drop error checking for debugfs_create_dir

[Osama Muhammad]

This patch fixes the error checking in adm1266.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.

Confusing. Is this v3 of the patch ?

[Osama Muhammad]

This is the new patch not v3. The patch I sent as v2 was a mistake.
Please discard the patch I sent earlier as v2 .
Apologies for the confusion.Hope it clarifies.

Osmten
