[PATCH v2 1/2] spi: core: Use %zu for printing 'size_t' type

[Fabio Estevam]

Use %zu for printing 'size_t' type in order to fix the following
build warning on ARM64:

drivers/spi/spi.c: In function '__spi_split_transfer_maxsize':
drivers/spi/spi.c:2278:2: warning: format '%i' expects argument of type 'int', but argument 4 has type 'size_t' [-Wformat=]

[PATCH v2 2/2] spi: core: Use min_t(size_t,..)

[Fabio Estevam]

Use min_t(size_t,..) in order to avoid the following 
build warning on ARM64:

  (void) (&_min1 == &_min2);  \

Thanks, was busy with other stuff and thus could not 
create a patch myself.

Applied "spi: core: Use min_t(size_t,..)" to the spi tree

[Mark Brown]

The patch

   spi: core: Use min_t(size_t,..)

has been applied to the spi tree at

   git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi.git 

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.  

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
