| |
3.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: "Luck, Tony" <tony.luck@intel.com>
commit 3bf3f8b19d2bfccc40f13c456bf339fd8f535ebc upstream.
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.
