Re: [PATCH 5/6] IP100A correct init and close step

["Jesse Huang" <jesse@icplus.com.tw>]

Hi Jeff:
(1)Should I change to :
spin_lock_irqsave(&np->lock,flags);
reset_tx(dev);
spin_lock_irqrestore(&np->lock,flags);

(2)I will remove date and author information out of source code comment.

NAK -- ineffective locking.

If you need locking here, you must use spin_lock_irqsave()

NAK:

1) date and author information is already present in the kernel
changelog.  It should not be present in the source code.

2) The comment (or patch description) fails to describe -why- this
change is needed.  It only described what is being changes, which is
already obvious from reading the source code.
