[PATCH] Fix ios_dev_stream_pread (was: Re: a warning in ios-dev-stream.c)

[Egeyar Bagcioglu]

Hello!

I have not been able to reproduce the warning on my system with
gcc version 10.2.1 20201125 (Red Hat 10.2.1-9) (GCC).

However, I see the problem with the code. Here is the patch I propose 
instead. Tested by hand and with the first poke filter.

Please review.
