| Subject: ACPI atomicio: Convert width in bits to bytes in __acpi_ioremap_fast() |
| |
| 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. |
