This patch removes the error checking for debugfs_create_dir in
pcmtest.c. This is because 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. The debugfs APIs have
a IS_ERR() judge in start_creating() which can handle it
gracefully. So these checks are unnecessary.
