[PATCH 1/2] device: fix enqueuing of characters in ttyinput_many

[Justus Winter]

Fix enqueuing of characters in ttyinput_many by wrapping the call to
b_to_q in a loop. This was probably intended by the authors, as they
subtract the number of enqueued characters from count.

Found using the Clang Static Analyzer.

* device/chario.c (ttyinput_many): Fix enqueuing of characters.
