3.2.77-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: "Janusz.Dziedzic@xxxxxxxxx" <Janusz.Dziedzic@xxxxxxxxx>
commit 4eeac22c159f053ea34527e4fea359ab10b4b5a5 upstream.
In corner case for wl12xx_spi_raw_write() when
len == SPI_AGGR_BUFFER_SIZE
we don't setup correctly spi transfer_list.
Next we will have garbage and strange errors
reported by SPI framework (eg. wrong speed_hz,
failed to transfer one message from queue)
when iterate transfer_list.
