Input: ams_delta_serio: Get FIQ buffer from platform_data
Instead of exporting the FIQ buffer symbol to be used in ams-delta-serio driver, pass it to the driver as platform_data. Signed-off-by: Janusz Krzysztofik <jmkrzyszt@gmail.com> Acked-by: Dmitry Torokhov <dmitry.torokhov@gmail.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
