[ Upstream commit 94b4cd7c5fc0dd6858a046b00ca729fb0512b9ba ]
The second parameter of spinlock_irq[save/restore] function is flags, which is the last input parameter of sf_pdma_prep_dma_memcpy().
So declare local variable 'iflags' to be used as the second parameter of spinlock_irq[save/restore] function.
