[PATCH] staging: media: parport: remove unused variable

[Aya Mahfouz <mahfouz.saif.elyazal@gmail.com>]

This patch uses the following coccinelle script to remove
a variable that was simply used to store the return
value of a function call before returning it:

@@
identifier len,f;
@@

-int len;
 ... when != len
     when strict
-len = 
+return 
	f(...);
-return len;
