Staging: ti-st: remove global references
Providing a context which can be passed around the driver, the KIM's platform driver's struct device to be used to dev_set_drvdata and dev_get_drvdata. The ST core's data is passed around using tty's disc_data and in other cases the ST KIM's platform device is exposed from the board-XX.c which adds KIM platform device whose dev is used. Thereby remove the need for the global reference struct kim_data_s *kim_gdata; Signed-off-by: NPavan Savoy <pavan_savoy@ti.com> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>
