[PATCH] accel/qaic: initialize ret variable to 0

From: Tom Rix
Date: Tue Apr 18 2023 - 15:22:37 EST


clang static analysis reports
drivers/accel/qaic/qaic_data.c:610:2: warning: Undefined or garbage
value returned to caller [core.uninitialized.UndefReturn]
return ret;
^~~~~~~~~~

The ret variable is only set some of the time but is always returned.
So initialize ret to 0.
