Subject: ATM firestream bug

The gcc warning "may be used uninitialized" is correct here, as well:

drivers/atm/firestream.c: In function ‘top_off_fp’:
drivers/atm/firestream.c:1501: warning: cast to pointer from integer of 
different size
drivers/atm/firestream.c: In function ‘fs_open’:
drivers/atm/firestream.c:870: warning: ‘tmc0’ may be used uninitialized 
in this function

This indicates two bugs:

1) not safe on 64-bit

2) variable 'tmc0' is indeed potentially used uninit'd, in particular if 
make_rate() returns an error (use occurs before error check).
