Patch queued for 4.12, thanks.

It seems that there are still some fbdev drivers with this issue:

$ git grep __exit_p drivers/video/fbdev/
drivers/video/fbdev/amifb.c:    .remove = __exit_p(amifb_remove),
drivers/video/fbdev/atmel_lcdfb.c:      .remove         = __exit_p(atmel_lcdfb_remove),
drivers/video/fbdev/omap2/omapfb/displays/connector-analog-tv.c:        .remove = __exit_p(tvc_remove),
drivers/video/fbdev/omap2/omapfb/displays/connector-dvi.c:      .remove = __exit_p(dvic_remove),
drivers/video/fbdev/omap2/omapfb/displays/connector-hdmi.c:     .remove = __exit_p(hdmic_remove),
drivers/video/fbdev/omap2/omapfb/displays/encoder-opa362.c:     .remove = __exit_p(opa362_remove),
drivers/video/fbdev/omap2/omapfb/displays/encoder-tfp410.c:     .remove = __exit_p(tfp410_remove),
drivers/video/fbdev/omap2/omapfb/displays/encoder-tpd12s015.c:  .remove = __exit_p(tpd_remove),
drivers/video/fbdev/omap2/omapfb/displays/panel-dpi.c:  .remove = __exit_p(panel_dpi_remove),
drivers/video/fbdev/omap2/omapfb/displays/panel-dsi-cm.c:       .remove = __exit_p(dsicm_remove),
drivers/video/fbdev/omap2/omapfb/displays/panel-sharp-ls037v7dw01.c:    .remove = __exit_p(sharp_ls_remove),
drivers/video/fbdev/omap2/omapfb/vrfb.c:        .remove         = __exit_p(vrfb_remove),

(these drivers don't disable sysfs bind/unbind attributes)

Could you please also take care of fixing them?

Best regards,
