[PATCH] media: ti: omap: release DSS compatibility layer on remove

[Guangshuo Li]

omap_vout_probe() calls omapdss_compat_init(), while omap_vout_remove()
does not call the corresponding omapdss_compat_uninit().

The probe failure paths release the DSS compatibility layer, but the
normal remove path leaves it initialized after the video output device
has been removed.

Call omapdss_compat_uninit() during remove after releasing the video
device resources, matching the cleanup performed by the probe failure
paths.

This issue was found by manual code inspection.
