I find 39 occurrences, although the first one I looked at had a big #if 0
in the module_init function. Here are some examples:

drivers/media/common/saa7146/saa7146_fops.c
drivers/media/platform/soc_camera/soc_mediabus.c
drivers/tty/serial/suncore.c

There are also a bunch of comedi drivers. Around half of the examples are
sound drivers, eg:

sound/synth/emux/emux.c
sound/synth/util_mem.c
sound/isa/sb/sb16_csp.c
