Subject: [PATCH] staging: vt6655: replace spin_lock_irqsave with spin_lock

In vt6655 driver, there is a single interrupt handler: vnt_interrupt(),
and it does not take the spinlock. The interrupt handler only schedules
a workqueue, and the spinlock is taken in this workqueue. Thus, there is
no need to use spin_lock_irqsave, as the spinlock is never taken by an
interrupt. Replace spin_lock_irqsave (and spin_unlock_irqsave) with
spin_lock (and spin_unlock).

Hi Nam,

I am lol ... my computer freezed (you don mind if I do not try this
patch again? Please send a v2) ;-)
I was digging for the log see below. (kern.log)
I hope you can do something with it.

Bye Philipp

What is the speed difference before and after this change? And how are
interrupts properly handled anymore in this driver if you took away the
lock that was being accessed in the irq?

Thank you so much for testing the patch and providing the log. I think my patch
introduces deadlock, which caused your computer to freeze. My bad, sorry about
that. I may send v2 in the future, when I fully understand what is going on.

Best regards,

My understanding is that no lock is accessed in the irq in this driver. But
it seems like I am wrong. Sorry for sending a buggy patch, I may follow-up with
this later when I figure out what I did wrong.

Best regards,
Nam.
