bus: ti-sysc: Fix dispc quirk masking bool variables
Fix warning drivers/bus/ti-sysc.c:1806 sysc_quirk_dispc() warn: masking a bool. While at it let's add a comment for what were doing to make the code a bit easier to follow. Fixes: 7324a7a0d5e2 ("bus: ti-sysc: Implement display subsystem reset quirk") Reported-by: Dan Carpenter <dan.carpenter@linaro.org> Closes: https://lore.kernel.org/linux-omap/a8ec8a68-9c2c-4076-bf47-09fccce7659f@kili.mountain/ Signed-off-by: Tony Lindgren <tony@atomide.com>
