 The first thing to do is to create:
 
 \begin{itemize}
-\item An \code{serial_write()} write file operation stub.
+\item A \code{serial_write()} write file operation stub.
       See the slides or the code for the prototype to use.
       Just place a \code{return -EINVAL;} statement in the function
       body so far, to signal that there is something wrong with this
       function so far.
-\item Similarly, an \code{serial_read()} read file operation stub.
+\item Similarly, a \code{serial_read()} read file operation stub.
 \item A \ksym{file_operations} structure declaring these file
       operations.
