This does not make sense to me. If request_firmware() is executing that
means some other module references it and module refcount already
reflects that.

We needed to pin module before Tejun's work ensuring that currently open
sysfs entries won't keep related kobjects pinned after kernel marked
them inactive. We can probably delete __module_get()/module_put() from
firmware_class.c now.

Thanks.
