hello there,
1.
[linux-4.4-rc8/drivers/platform/x86/thinkpad_acpi.c:2297] -> [linux-4.4-rc8/drivers/platform/x86/thinkpad_acpi.c:3694]: (warning) Shifting 32-bit value by 51 bits is undefined behaviour. See condition at line 3694.
Source code at line 2297 is
if (hotkey_user_mask & (1 << scancode))
and at 3694 is
if (scancode> 0 && scancode <= TPACPI_HOTKEY_MAP_LEN) {
Maybe new code
if (hotkey_user_mask & (1UL << scancode))
is better.
2.
[linux-4.4-rc8/drivers/platform/x86/thinkpad_acpi.c:3696] -> [linux-4.4-rc8/drivers/platform/x86/thinkpad_acpi.c:3694]: (warning) Shifting 32-bit value by 51 bits is undefined behaviour. See condition at line 3694.
Duplicate.
