[PATCH -next v2 00/21] spi: switch to use modern name (part3)

[PATCH -next v2 00/21] spi: switch to use modern name (part3)

[Yang Yingliang]

I'm trying to rename the legacy name to modern name used in SPI drivers,
this is part3 patchset.

After introducing devm_spi_alloc_host/spi_alloc_host(), the legacy
named function devm_spi_alloc_master/spi_alloc_master() can be replaced.
And also change other legacy name master/slave to modern name host/target
or controller. Each patch compile test passed.

v1 -> v2:
In patch #3, #4, #5, #6, #7, #11,
keep some registers and comments using old name to fit with documentation.

Yang Yingliang (21):

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
