Re: [PATCH] ACPI: Test for ACPI_SUCCESS rather than !ACPI_FAILURE

The double negative makes it hard to read "if (!ACPI_FAILURE(status))". Replace it with "if (ACPI_SUCCESS(status))".

This isn't really an ACPI patch, but I'm sending it to you, Rafael, since it seems easier to just apply these all at once. But I'd be happy to split them up into individual patches if you'd rather.

Thanks, everybody. Rafael, I'll just merge this via my tree to avoid burdening you.
