> Subject: [PATCH] dma/idxd: fix return value for pci device commands
> 
> When sending a command to an idxd device via pci bar, the response from
> HW is checked to ensure it was successful. The response was incorrectly
> being negated before being returned by the function, meaning error codes
> cannot be checked against the HW specification.
> 
> This patch fixes the return values of the function by removing the
> negation.
