There is no point in calling dma_supported() before calling
dma_set_coherent_mask(). This function already calls dma_supported() and
returns an error (-EIO) if it fails.
So remove the superfluous dma_supported() call.
Moreover, setting a larger DMA mask will never fail when setting a smaller
one will succeed, so the whole "while" loop can be removed as well. (see
[1])
While at it, fix the name of the function reported in a dev_err().
