drivers/sound/sound_core.c:soundcore_open:

spin_lock(&sound_loader_lock);
if (s)
0x51d <soundcore_open+77>: testl %ebx,%ebx
0x51f <soundcore_open+79>: je 0x554 <soundcore_open+132>

new_fops = fops_get(s->unit_fops);
0x521 <soundcore_open+81>: movl 0x4(%ebx),%eax

#define fops_get(fops) \
(((fops) && (fops)->owner) \
? ( try_inc_mod_count((fops)->owner) ? (fops) : NULL ) \
: (fops))
^^^^^^^^^^^^ Bang!
0x524 <soundcore_open+84>: testl %eax,%eax
0x526 <soundcore_open+86>: je 0x550 <soundcore_open+128>
0x528 <soundcore_open+88>: movl (%eax),%edx <=====
0x52a <soundcore_open+90>: testl %edx,%edx
