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).
