Tested together with - iio: Fix: Do not poll the driver again if try_reenable() callback returns non 0. and - iio:trigger: rename try_reenable() to reenable() plus return void on latest mainline (without PREEMPT_RT). The original WARN_ONCE() in kernel/irq/handle.c:159 was not raised anymore. But even without the current patches, this warning is not shown (as this problem only applies to -RT). Currently I haven't ported a RT kernel > 5.4 for my board, so I cannot check with current RT. On 5.4. there the patches seem not to work fully as kernel/timer/hrtimer.c is not up to date enough. Sorry for being not very helpful...
