Subject: [PATCH] drivers/net/wireless/iwlwifi/iwl-3945.c Fix type issue on
	64bit

>> What about the format line in the IWL_DEBUG_RX that uses rate?

I had figured that as rate was only positive it would work as is.
However you are dead right, there is no point in a patch removing one
example of bad programming only to introduce another.

Here is the updated patch:


Coverity CID: 2265 NEGATIVE_RETURNS

"rate" is of an unsigned type, and the code requires a signed type.
The following patch makes it so.
