From 2ee177e945e000a40b520ea667fd4fbe7a61634e Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Thu, 31 Dec 2015 09:56:03 +0100 Subject: [PATCH] irq_poll: Fix irq_poll_sched() The IRQ_POLL_F_SCHED bit is set as long as polling is ongoing. This means that irq_poll_sched() must proceed if this bit has not yet been set. Fixes: commit ea51190c0315 ("irq_poll: fold irq_poll_sched_prep into irq_poll_sched").
