sys/dev/acpi/acpi_ec.c: revision 1.77
- Fix a bug that acpiec_space_handler() doesn't access more than 64bit
correctly. Found by kUBSan on Thinkpad X220. acpiec0 accessed 128bits from
address 0xa0. The error message was:
UBSan: Undefined Behavior in ../../../../dev/acpi/acpi_ec.c:672:32,
shift exponent 64 is too large for 64-bit type 'long unsigned int'
- KNF.
- Make the case that width < 8 behave as the same as before. Pointed out by
Joerg.
- Change "switch" to "if" for simplify.
