Subject: [PATCH -next] ACPI: processor: Fix a prepocessor warning
Date: Thu, 1 Apr 2021 10:39:00 +0800 [thread overview]
Message-ID: <20210401023900.3114325-1-liushixin2@huawei.com> (raw)
When compiling with defconfig on x86_64, I got a warning:
drivers/acpi/processor_idle.c: In function ‘acpi_idle_play_dead’:
drivers/acpi/processor_idle.c:542:15: warning: extra tokens at end of #ifdef directive
542 | #ifdef defined(CONFIG_X86) && defined(CONFIG_HOTPLUG_CPU)
|
Fixes: bc5706eaeae0 ("ACPI: processor: Fix CPU0 wakeup in acpi_idle_play_dead()")
