To enumerate all standards applications shall begin at index
zero, incrementing by one until the driver returns EINVAL.
The actual code, however, tests the index this way:
if (index<=0 || index >= vfd->tvnormsize) {
ret=-EINVAL;
So any application which passes in index=0 gets EINVAL right off the bat

[PATCH] load_module: no BUG if module_subsys uninitialized
Invoking load_module() before param_sysfs_init() is called crashes in
mod_sysfs_setup(), since the kset in module_subsys is not initialized yet.
In my case, net-pf-1 is getting modprobed as a result of hotplug trying to
create a UNIX socket. Calls to hotplug begin after the topology_init
initcall.
Another patch for the same symptom (module_subsys-initialize-earlier.patch)
moves param_sysfs_init() to the subsys initcalls, but this is still not
early enough in the boot process in some cases. In particular,
topology_init() causes /sbin/hotplug to run, which requests net-pf-1 (the
UNIX socket protocol) which can be compiled as a module. Moving
param_sysfs_init() to the postcore initcalls fixes this particular race,
but there might well be other cases where a usermodehelper causes a module
to load earlier still.
The patch makes load_module() return an error rather than crashing the
kernel if invoked before module_subsys is initialized.
