I can only guess that this falls under ZR36067 ?? (cc's added)

Subject: zoran drivers: absense of locking?
I've tried to read random part of a tree and now scratching my head
with a question:
what protects the number and a list of registered codecs in
zoran drivers?
Example: drivers/media/video/zr36050.c:
/* amount of chips attached via this driver */
static int zr36050_codecs = 0;
Decremented in zr36050_unset().
Checked for maximum value, used and incremented in zr36050_setup().
[Assigment to 0 in zr36050_init_module is not needed. dprintk() in
zr36050_cleanup_module() should be converted to BUG_ON, so I'll ignore
them.]
zr36050_codecs
zr36050_unset() = struct videocodec::unset
zr36050_setup() = struct videocodec::setup
The only place where ->unset and ->setup methods are called is
drivers/media/video/videocodec.c:
zr36050_codecs
zr36050_unset()
videocodec_detach()
zr36050_setup()
videocodec_attach()
Both videocodec functions are exported.
No spinlocks or semaphores in sight.
Does anybody know what protects the list of registered codecs in zoran
drivers?
