From 3bd81a8710710f8bf5d1a5ebac315c842c20bdd3 Mon Sep 17 00:00:00 2001 From: Thomas Renninger Date: Tue, 17 Jan 2012 22:40:07 +0100 Subject: ACPI processor: Remove unneeded variable passed by acpi_processor_hotadd_init V2 V2: Fix typo: pr->handle -> pr, here: acpi_processor_hotadd_init(pr) This is a very small part taken from patches which afaik are coming from Yunhong Jiang (for a Xen not a Linus repo?). Cleanup only: no functional change. Advantage (beside cleanup) is that other data of the pr (acpi_processor) struct in the acpi_processor_hotadd_init() is needed later, for example a newly introduced flag: pr->flags.need_hotplug_init Signed-off-by: Thomas Renninger CC: Bjorn Helgaas CC: Jiang, Yunhong Signed-off-by: Len Brown --- drivers/acpi/processor_driver.c | 17 ++++++++--------- 1 file changed, 8 insertions(+), 9 deletions(-) (limited to 'drivers/acpi') diff --git a/drivers/acpi/processor_driver.c b/drivers/acpi/processor_driver.c index 3616ce5509c..b9cbd9b0945 100644 --- a/drivers/acpi/processor_driver.c +++ b/drivers/acpi/processor_driver.c @@ -82,7 +82,7 @@ MODULE_LICENSE("GPL"); static int acpi_processor_add(struct acpi_device *device); static int acpi_processor_remove(struct acpi_device *device, int type); static void acpi_processor_notify(struct acpi_device *device, u32 event); -static acpi_status acpi_processor_hotadd_init(acpi_handle handle, int *p_cpu); +static acpi_status acpi_processor_hotadd_init(struct acpi_processor *pr); static int acpi_processor_handle_eject(struct acpi_processor *pr); @@ -324,10 +324,8 @@ static int acpi_processor_get_info(struct acpi_device *device) * they are physically not present. */ if (pr->id == -1) { - if (ACPI_FAILURE - (acpi_processor_hotadd_init(pr->handle, &pr->id))) { + if (ACPI_FAILURE(acpi_processor_hotadd_init(pr))) return -ENODEV; - } } /* * On some boxes several processors use the same processor bus id. @@ -721,18 +719,19 @@ processor_walk_namespace_cb(acpi_handle handle, return (AE_OK); } -static acpi_status acpi_processor_hotadd_init(acpi_handle handle, int *p_cpu) +static acpi_status acpi_processor_hotadd_init(struct acpi_processor *pr) { + acpi_handle handle = pr->handle; if (!is_processor_present(handle)) { return AE_ERROR; } - if (acpi_map_lsapic(handle, p_cpu)) + if (acpi_map_lsapic(handle, &pr->id)) return AE_ERROR; - if (arch_register_cpu(*p_cpu)) { - acpi_unmap_lsapic(*p_cpu); + if (arch_register_cpu(pr->id)) { + acpi_unmap_lsapic(pr->id); return AE_ERROR; } @@ -749,7 +748,7 @@ static int acpi_processor_handle_eject(struct acpi_processor *pr) return (0); } #else -static acpi_status acpi_processor_hotadd_init(acpi_handle handle, int *p_cpu) +static acpi_status acpi_processor_hotadd_init(struct acpi_processor *pr) { return AE_ERROR; } -- cgit v1.2.3-18-g5258
