[PATCH 1/2] ALSA: firewire-tascam: Fix infinite loop in snd_tscm_stream_get_rate()

[Geert Uytterhoeven]

Obviously the intention was to put a limit on the maximum number of
operations.  However, for this to work, the check should be
"&& trials++ < 5", not "|| trials++ < 5".

Fixes: 35efa5c489de63a9 ("ALSA: firewire-tascam: add streaming functionality")

Compile-tested only.

Triggered by a false-positive warning from gcc-4.1.2:

    warning: ‘err’ may be used uninitialized in this function
