In halbtc8723b2ant_TdmaDurationAdjust function,below piece of code is
repeated many times.
halbtc8723b2ant_PsTdma(pBtCoexist, NORMAL_EXEC, true, val);
pCoexDm->psTdmaDuAdjType = val;
So replace the same with "HAL_BTC8723B2ANT_DMA_DURATION_ADJUST" MACRO.

Recent changes have made it much more likely that clocks are not available,
when the SDHCI driver is first probed. However, that is a situation that
the driver can cope with just fine.
To avoid confusion, don't output an error when this happens.

The calculation of slots results in a value in the range 1..8
and so slots can never be zero. The check for slots == 0 is
always going to be false, hence it is redundant and can be

If bus_register fails. On its error handling path, it has cleaned up
what it has done. There is no need to call bus_unregister again.

On the Amlogic G12A SoC family, (only) the SDIO controller fails to access
the data from DRAM, leading to a broken controller.
But each MMC controller has 1,5KiB of SRAM after the registers, that can
be used as bounce buffer to avoid direct DRAM access from the integrated
DMAs (this SRAM may be used by the boot ROM when DRAM is not yet initialized).
The quirk is to disable the chained descriptor for this controller, and
use this SRAM memory zone as buffer for the bounce buffer fallback mode.
The performance hit hasn't been evaluated, but the fix has been tested
using a WiFi AP6398S SDIO module, and the iperf3 Bandwidth measurement gave
55.2 Mbits/sec over a 63 Hours long test, with the SDIO ios set as High-Speed
at 50MHz clock. It gave 170 Mbits/sec as SDR104 and 200MHz clock.

Both the Renesas and Uniphier implementations perform actions which
affect runtime PM before calling into the core tmio_mmc_host_probe()
which enabled runtime PM. Move pm_runtime_enable() from the core and
tmio_mmc_host_probe() into each drivers probe() so it can be called
before any clocks or other resources are switched on.

The driver for android-goldfish uses a pointer to get from the private
goldfish_mmc_host structure to the generic mmc_host structure.
However the latter is always immediately preceding the former in
memory, so compute its address with a subtraction (which is cheaper than a
dereference) and drop the superfluous pointer.
No functional change intended.

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:
struct spi_replaced_transfers {
...
struct spi_transfer inserted_transfers[];
};
Make use of the struct_size() helper instead of an open-coded version
in order to avoid any potential type mistakes.
So, replace the following form:
insert * sizeof(struct spi_transfer) + sizeof(struct spi_replaced_transfers)
with:
struct_size(rxfer, inserted_transfers, insert)
This code was detected with the help of Coccinelle.
