[ATM] firestream: handle thrown error
gcc emits the following warning: drivers/atm/firestream.c: In function ‘fs_open’: drivers/atm/firestream.c:870: warning: ‘tmc0’ may be used uninitialized in this function This indicates a real bug. We should check make_rate() return value for potential errors. Signed-off-by: Jeff Garzik <jeff@garzik.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: David S.
