Subject: [PATCH] preempt/dynamic: Fix setup_preempt_mode() return value
Date: Fri, 3 Dec 2021 17:32:03 -0600 [thread overview]
Message-ID: <20211203233203.133581-1-ahalaney@redhat.com> (raw)
__setup() callbacks expect 1 for success and 0 for failure. Correct the
usage here to reflect that.
Fixes: 826bfeb37bb4 ("preempt/dynamic: Support dynamic preempt with preempt= boot option")
Reported-by: Mark Rutland <mark.rutland@arm.com>
Signed-off-by: Andrew Halaney <ahalaney@redhat.com>
