Subject[PATCH 5.9 085/152] bus: ti-sysc: suppress err msg for timers used as clockevent/source
Date
From: Grygorii Strashko <grygorii.strashko@ti.com>

[ Upstream commit 65fb73676112f6fd107c5e542b2cbcfb206fe881 ]

GP Timers used as clockevent/source are not available for ti-sysc bus and
handled by Kernel timekeeping core. Now ti-sysc produces error message
every time such timer is detected:

"ti-sysc: probe of 48040000.target-module failed with error -16"

Such messages are not necessary, so suppress them by returning -ENXIO
instead of -EBUSY.

Fixes: 6cfcd5563b4f ("clocksource/drivers/timer-ti-dm: Fix suspend and resume for am3 and am4")
