bus: ti-sysc: Fix error handling for sysc_check_active_timer()
We have changed the return type for sysc_check_active_timer() from -EBUSY to -ENXIO, but the gpt12 system timer fix still checks for -EBUSY. We are also not returning on other errors like we did earlier as noted by Pavel Machek <pavel@denx.de>. Commit 3ff340e24c9d ("bus: ti-sysc: Fix gpt12 system timer issue with reserved status") should have been updated for commit 65fb73676112 ("bus: ti-sysc: suppress err msg for timers used as clockevent/source"). Let's fix the issue by checking for -ENXIO and returning on any other errors as suggested by Pavel Machek <pavel@denx.de>. Fixes: 3ff340e24c9d ("bus: ti-sysc: Fix gpt12 system timer issue with reserved status") Depends-on: 65fb73676112 ("bus: ti-sysc: suppress err msg for timers used as clockevent/source") Reported-by: Pavel Machek <pavel@denx.de> Reviewed-by: Pavel Machek (CIP) <pavel@denx.de> Cc: Grygorii Strashko <grygorii.strashko@ti.com> Cc: Jarkko Nikula <jarkko.nikula@bitmer.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
