No, this is now worse looking.  The original was not pretty, but better
than this.

thanks,

This isn't really a fix, but instead is a change to make
the code more like typical coding style.

More typical would be to have the return value on a separate line
as using * on the start of a line is poor form in the kernel.

static struct dma_async_tx_descriptor *
mtk_hsdma_prep_dma_memcpy(struct dma_chan *c, dma_addr_t dest, dma_addr_t src,
			  size_t len, unsigned long flags)
{
	...
}
