Subject: [PATCH 3.2 058/164] spi: pl022: Fix incorrect dma_unmap_sg

3.2.65-rc1 review patch.  If anyone has any objections, please let me know.


From: Ray Jui <>

commit 3ffa6158f002e096d28ede71be4e0ee8ab20baa2 upstream.

When mapped RX DMA entries are unmapped in an error condition when DMA
is firstly configured in the driver, the number of TX DMA entries was
passed in, which is incorrect
