[PATCH] atm/firestream: handle thrown error

From: Jeff Garzik
Date: Tue Oct 10 2006 - 03:32:36 EST



gcc emits the following warning:

drivers/atm/firestream.c: In function âfs_openâ:
drivers/atm/firestream.c:870: warning: âtmc0â may be used uninitialized in this function

This indicates a real bug. We should check make_rate() return value for
potential errors.
