[PATCH v2 12/16] drm/mipi-dsi: move to_mipi_dsi_device() to use container_of_const()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The driver core is changing to pass some pointers as const, so move
to_mipi_dsi_device() to use container_of_const() to handle this change.

to_mipi_dsi_device() now properly keeps the const-ness of the pointer passed
into it, while as before it could be lost.
