Dan Carpenter 44e151be23 accel/ivpu: prevent uninitialized data bug in debugfs 
The simple_write_to_buffer() will only initialize data starting from
the *pos offset so if it's non-zero then the first part of the buffer
uninitialized.  Really, if *pos is non-zero then this code won't work
so just check for that at the start of the function.
