Add a macro to check for a quirk because it a) ensures that the check for non-empty 'quirks' struct is not forgotten and b) is easier to read. Convert existing quirk access as well. Signed-off-by:

Up to now, HS400 adjustment mode was only disabled on soft reset when a calibration table was in use. It is safer, though, to disable it as soon as the instance has an adjustment related quirk set, i.e. bad taps or a calibration table. Signed-off-by:

There is only one alignment shift for one type of Renesas SDHI. Encode it directly in its DMA driver to reduce complexity and ease further simplifications. Signed-off-by:

After a8402aed8ca5 ("mmc: tmio_mmc_core: Remove local_irq_{save,restore}() around k[un]map_atomic()") and ac91578a6812 ("mmc: tmio_mmc_core: Replace kmap_atomic() with kmap_local_page()"), the helpers contain just a single call. Putting it directly in the code makes it actually more readable. More so, because we now avoid the 'offset' calculation when mapping/unmapping and just use it when we need it in the copy routines.

So far, we have been relying on access_end interrupts only to mark DMA transfers as done implying that DMA end interrupts have occurred by then anyhow. On some SoCs under some conditions, this turned out to be not enough. So, we enable DMA interrupts as well and make sure that both events, DMA irq and access_end irq, have happened before finishing the DMA transfer. Signed-off-by:

Commit 058db286 ("mmc: tmio, renesas_sdhi: move struct tmio_mmc_dma to renesas_sdhi.h") is correct. The DMA struct should be prefixed with 'renesas_sdhi' to avoid confusion about is namespace. Fix some indentation while here. Signed-off-by:

This accessor function does not help readability but makes it worse. Because I soon need to read from the registers as well and don't want to add another function like this, I chose to remove the existing one and use the accessor directly. I also switch from writeq to writel because no 64 bit register is actually involved. Signed-off-by:

mmc_add_host() may return error, if we ignore its return value, it will lead two issues: 1. The memory that allocated in mmc_alloc_host() is leaked. 2. In the remove() path, mmc_remove_host() will be called to delete device, but it's not added yet, it will lead a kernel crash because of null-ptr-deref in device_del(). So fix this by checking the return value and goto error path which will call mmc_free_host(). Fixes: 1da177e4 ("Linux-2.6.12-rc2") Signed-off-by:
