From: Hans de Goede Date: Wed, 24 Apr 2024 12:28:26 +0000 (+0200) Subject: platform/x86: thinkpad_acpi: Change hotkey_reserved_mask initialization X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d3272c744518b3ccecec12c1e1dd4366f69d0854;p=linux.git platform/x86: thinkpad_acpi: Change hotkey_reserved_mask initialization Change the hotkey_reserved_mask initialization to hardcode the list of reserved keys. There are only a few reserved keys and the code to iterate over the keymap will be removed when moving to sparse-keymaps. Note only the 32 original hotkeys are affected by the hotkey_*_mask values: if (i < sizeof(hotkey_reserved_mask)*8) hotkey_reserved_mask |= 1 << i; The (i < sizeof(hotkey_reserved_mask)*8) condition translates to (i < 32) so this code only ever set bits in hotkey_reserved_mask for the 32 original hotkeys. Therefor this patch does not set any bits in hotkey_reserved_mask for the KEY_RESERVED mappings for the adaptive keyboard scancodes.
