Now you have two different checks for the same, I would suggest that you switch to check clk->cl in the skl_int3472_enable_clk() as it's done in the skl_int3472_register_dsm_clock() instead of GPIO. Other way around is also possible but it seems to me that checking for clock existence has better guarantees than just checking for GPIO availability. -- With Best Regards, Andy Shevchenko
