Subject: [PATCH 4.2.y-ckt 090/211] toshiba_acpi: Initialize hotkey_event_type variable

4.2.8-ckt1 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Azael Avalos <coproscefalo@...il.com>

commit d2f20619942fe4618160a7fa3dbdcbac335cff59 upstream.

Commit 53147b6cabee5e8d1997b5682fcc0c3b72ddf9c2 ("toshiba_acpi: Fix
hotkeys registration on some toshiba models") fixed an issue on some
laptops regarding hotkeys registration, however, if failed to address
the initialization of the hotkey_event_type variable, and thus, it can
lead to potential unwanted effects as the variable is being checked.

This patch initializes such variable to avoid such unwanted effects.
