[PATCH][2.4.28-pre3] USB drivers gcc-3.4 fixes

[Mikael Pettersson]

This patch fixes gcc-3.4 cast-as-lvalue warnings in the 2.4.28-pre3
kernel's USB drivers. The audio.c and uss720.c changes are backports
from the 2.6 kernel. The hpusbscsi.c and microtek.c changes are new,
since the 2.6 code is different.
