ACPICA: Fix 'may be used uninitialized' warning in acpi_ns_repair_object()

2017-11-11T13:34:41Z

gcc 4.7 warns that new_object may be used uninitialized in this function. In fact, all the cases where it's not initialised are errors that will result in returning early without using it. Silence the warning by initialising to NULL. This was done upstream as part of commit d5a36100f62f "ACPICA: Add mechanism for early object repairs on a per-name basis". Signed-off-by: Ben Hutchings

ACPICA: Tables: Fix an issue that FACS initialization is performed twice

2015-08-12T14:33:18Z

commit c04be18448355441a0c424362df65b6422e27bda upstream. ACPICA commit 90f5332a15e9d9ba83831ca700b2b9f708274658 This patch adds a new FACS initialization flag for acpi_tb_initialize(). acpi_enable_subsystem() might be invoked several times in OS bootup process, and we don't want FACS initialization to be invoked twice.

ACPICA: Utilities: Cleanup to remove useless ACPI_PRINTF/FORMAT_xxx helpers.

2015-08-06T23:32:20Z

commit 1d0a0b2f6df2bf2643fadc990eb143361eca6ada upstream. ACPICA commit b60612373a4ef63b64a57c124576d7ddb6d8efb6 For physical addresses, since the address may exceed 32-bit address range after calculation, we should use 0x%8.8X%8.8X instead of ACPI_PRINTF_UINT and ACPI_FORMAT_UINT64() instead of ACPI_FORMAT_NATIVE_UINT()/ACPI_FORMAT_TO_UINT(). This patch also removes above replaced macros as there are no users. This is a preparation to switch acpi_physical_address to 64-bit on 32-bit kernel builds.
