commit ceaea851b9ea75f9ea2bbefb53ff0d4b27cd5a6e upstream.
Back in ff9fb72bc07705c (debugfs: return error values, not NULL) the debugfs APIs were changed to return error pointers rather than NULL pointers on error, breaking the error checking in ASoC. Update the code to use IS_ERR() and log the codes that are returned as part of the error messages.
