DMA-API: net: brocade/bna/bnad.c: fix 32-bit DMA mask handling
The fallback to 32-bit DMA mask is rather odd:
if (!dma_set_mask(&pdev->dev, DMA_BIT_MASK(64)) &&
!dma_set_coherent_mask(&pdev->dev, DMA_BIT_MASK(64))) {
*using_dac = true;
} else {
err = dma_set_mask(&pdev->dev, DMA_BIT_MASK(32));
if (err) {
err = dma_set_coherent_mask(&pdev->dev,
DMA_BIT_MASK(32));
if (err)
goto release_regions;
}
This means we only try and set the coherent DMA mask if we failed to
set a 32-bit DMA mask, and only if both fail do we fail the driver.
Adjust this so that if either setting fails, we fail the driver - and
thereby end up properly setting both the DMA mask and the coherent
DMA mask in the fallback case.
