spi: change clk_disable_unprepare to clk_unprepare

2021-12-29T11:20:43Z

[ Upstream commit db6689b643d8653092f5853751ea2cdbc299f8d3 ] The corresponding API for clk_prepare is clk_unprepare, other than clk_disable_unprepare. Fix this by changing clk_disable_unprepare to clk_unprepare.

spi: spi-pic32: Fix issue with uninitialized dma_slave_config

2021-09-22T09:47:51Z

[ Upstream commit 976c1de1de147bb7f4e0d87482f375221c05aeaf ] Depending on the DMA driver being used, the struct dma_slave_config may need to be initialized to zero for the unused data. For example, we have three DMA drivers using src_port_window_size and dst_port_window_size. If these are left uninitialized, it can cause DMA failures. For spi-pic32, this is probably not currently an issue but is still good to fix though.

spi: meson-spicc: fix memory leak in meson_spicc_remove

2021-08-12T11:19:44Z

commit 8311ee2164c5cd1b63a601ea366f540eae89f10e upstream. In meson_spicc_probe, the error handling code needs to clean up master by calling spi_master_put, but the remove function does not have this function call. This will lead to memory leak of spicc->master.

spi: mediatek: Fix fifo transfer

2021-08-08T06:54:30Z

commit 0d5c3954b35eddff0da0436c31e8d721eceb7dc2 upstream. Commit 3a70dd2d0503 ("spi: mediatek: fix fifo rx mode") claims that fifo RX mode was never handled, and adds the presumably missing code to the FIFO transfer function. However, the claim that receive data was not handled is incorrect. It was handled as part of interrupt handling after the transfer was complete. The code added with the above mentioned commit reads data from the receive FIFO before the transfer is started, which is wrong. This results in an actual transfer error on a Hayato Chromebook. Remove the code trying to handle receive data before the transfer is started to fix the problem.
