Subject: linux-next: build failure after merge of the staging tree

Hi all,

After merging the staging tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/iio/trigger/iio-trig-sysfs.c: In function 'iio_sysfs_trigger_probe':
drivers/iio/trigger/iio-trig-sysfs.c:164:21: error: 'struct irq_work' has no member named 'flags'
  164 |  atomic_set(&t->work.flags, IRQ_WORK_HARD_IRQ);
      |                     ^

Caused by commit

  0449fc4eead7 ("iio: sysfs-trigger: Mark irq_work to expire in hardirq context")

interacting with commit

  7a9f50a05843 ("irq_work: Cleanup")

from the tip tree.

I applied the following merge fix patch:

Subject: [PATCH] fixup for "irq_work: Cleanup"
