ACPI atomicio: Convert width in bits to bytes in __acpi_ioremap_fast()
Luck, Tony [Fri, 21 Oct 2011 21:42:55 +0000 (14:42 -0700)]
Callers to __acpi_ioremap_fast() pass the bit_width that they found in the
acpi_generic_address structure. Convert from bits to bytes when passing to
__acpi_find_iomap() - as it wants to see bytes, not bits.
