3.2.77-rc1 review patch. If anyone has any objections, please let me know.
------------------ From: "[email protected]" <[email protected]> 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.
