pi433_write requires locking due to multiple writers. After acquiring the lock check if enough free space is available in the kfifo to write the whole message. This check should prevent partial writes to tx_fifo so kfifo_reset is not needed anymore. pi433_tx_thread is the only reader so it does not require locking after kfifo_reset is removed.

We should get drvdata from struct device directly. Going via platform_device is an unneeded step back and forth. Signed-off-by:

The current default transfer is to use DMA or not depending on the size of the data. The upstream driver mtk-sd uses DMA all times, change the standard mode here to DMA for testing, if there are any performance problems with DMA for small data sizes. If not, the option for transfer mode should be removed in the future, Signed-off-by:

The msdc_init_gpd_bd function is currently hard to read, because of old, commented out code and a while loop, where a for loop is much easier to read. Refactor it to make the code more readable. Signed-off-by:

The xfersz field of msdc_dma is only set to host->xfer_size and this is also available at the (few) positions, where dma.xfersz is used, so it is removed. Signed-off-by:

The flags of msdc_dma are set to a constant value, so block and dword padding are disabled and checksum is enabled. By removing the field the code is easier to read and the difference to the mtk-sd driver is smaller. Signed-off-by:

The fields used_gpd|bd in struct msdc_dma are only set and reset, but never used, so remove them. The other removed fields are never used, so they were removed either. Signed-off-by:

Currently the msdc_dma_config function has some variables, that are not needed, uses the macro msdc_init_bd that is only used here and does not use the for_each_sg iterator. That last fact could cause a bug if the scatterlist is chained. The function is changed to remove these things, but none of the changes should change the behavior of it (despite the case of a linked scatterlist). Signed-off-by:

The msdc_dma_dump function is disabled by a preprocessor macro, was only used in the msdc_dma_setup function. The code also contains no information about the device, it only dumps some memory for debug. Signed-off-by:

The burstsz field in msdc_dma is set to a constant value and later only used two times, using the constant directly in that places allows to remove the field and improves readability. Signed-off-by:

Current code just busy waits with nop for clock becoming stable, relaxing the cpu here improves readability and portability and also removes a unnecessary difference with the mtk-sd driver. Signed-off-by:

In the current code the hardware reset is realised via a macro and does only wait for a certain ammount of time for the controller to come out of reset state, but it should wait until it IS out of reset state. So it is refactored to improve this, it is also changed from a macro to a function and renamed to msdc_reset_hw to match the mtk-sd driver. Signed-off-by:

The enable|disable_sdio_irq() fields of msdc_hw are never set, so when they are called, they are null pointer. In case of the MSDC_EXT_SDIO_IRQ flag set in msdc0_hw, this happens. But because these fields are never set, they can simply be removed. Signed-off-by:

If the debug file in proc fs is not successfully created current code prints an error message, this is removed. de is also not an error pointer, so the IS_ERR() call leads to a static checker warning. The unused return value of the msdc_debug_proc_init function is also removed. Reported-by:
