The descriptor unmapping code introduced in commit
d38a8c622a1b3 "dmaengine: prepare for generic 'unmap' data"
accidentally affects a local struct rather than the
async TX descriptor, resulting in this compile error:
CC drivers/dma/amba-pl08x.o
drivers/dma/amba-pl08x.c: In function ‘pl08x_desc_free’:
drivers/dma/amba-pl08x.c:1172:2: warning: passing argument 1 of
‘dma_descriptor_unmap’ from incompatible pointer type [enabled by default]
