This is one of the most interesting users of module parameters in the
tree, so weaning it off the old-style non-const module_param_call
scheme is a useful exercise.
I was confused by set_param_int/get_param_int (vs. the normal
param_set_int and param_get_int), so I renamed set_param_int to
set_param_timeout, and re-used param_get_int directly instead of
get_param_int. I also implemented param_check_wdog_ifnum and
param_check_timeout, so now the ifnum_to_use and timeout/pretimeout
parameters can just use plain module_param().

There may be cases (most obviously, sysfs-writable charp parameters) where
a module needs to prevent sysfs access to parameters.
Rather than express this in terms of a big lock, the functions are
expressed in terms of what they protect against. This is clearer, esp.
if the implementation changes to a module-level or even param-level lock.

Instead of using a "I kmalloced this" flag, we keep track of the kmalloced
strings and use that list to check if we need to kfree (in practice, the
list is very short).
This means that kparams can be const again, and plugs a leak. This
is important for drivers/usb/gadget/nokia.c which gets modprobe/rmmod'ed
frequently on the N9000.
