[PATCH] toshiba_acpi: Initialize hotkey_event_type variable

[PATCH] toshiba_acpi: Initialize hotkey_event_type variable

[Azael Avalos]

Commit 23f8f4326a15 ("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.

It's a trivial patch, so I'm not concerned with the timing. Thanks for getting
it out!

Unfortunately, it doesn't apply and appears to be whitespace mangled. Checkpatch
complains and tabs appear to have been replaced with spaces. Please check your
send mail mechanism and resend - possibly using git-send-email or something like
mutt -H PATCHNAME. Try sending to yourself first and verifying you can apply it.

Thanks,

Ughh, sorry about this, I sent this email directly instead of git-send-email,
so the copy-paste might have changed something.

The version of git I'm currently using parses the stable address as
stable@vger.kernel.org#4.1+ and gsmtp complains about a malformed address...

I'll try to resend this patch ASAP.
