leds: ledtrig-tty: Free allocated ttyname buffer on deactivate
The ttyname buffer for the ledtrig_tty_data struct is allocated in the sysfs ttyname_store() function. This buffer must be released on trigger deactivation. This was missing and is thus a memory leak. While we are at it, the TTY handler in the ledtrig_tty_data struct should also be returned in case of the trigger deactivation call.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
