Re: [PATCH v4] HID: appletb-kbd: support layer switching on Fn double press

Holding Fn temporarily switches the Touch Bar between media controls and
function keys. Users who want to keep the alternate layer currently need
to change the mode through sysfs.

An optional double_press_switch_time module parameter makes a double press
persistently switch the default layer. Its value specifies the double-press
interval in milliseconds, while zero leaves the behavior disabled.

Changes in v2:
- Added a check to ensure negative fn switch times are ignored.

Changes in v3:
- Renamed the backing variable to match the module parameter.
- Fixed the reported code style issues.

Changes in v4:
- Added missing "break;" in case statements.
- Change author's email to aditya.garg@linux.dev

Now that I see it, the case statements were ending in return. break was not needed. Sorry for the brainfart.
