This change reports a warning when "default n" is used.
I have seen several "remove default n" patches, so I think
it might be helpful to add this test in checkpatch.
tested:
WARNING: 'default n' is the default value, no need to write it explicitly.
+ default n

I don't think this is reasonable as there are
several uses like:
default y
default n if <foo>
For instance:
arch/alpha/Kconfig-config ALPHA_WTINT
arch/alpha/Kconfig- bool "Use WTINT" if ALPHA_SRM || ALPHA_GENERIC
arch/alpha/Kconfig- default y if ALPHA_QEMU
arch/alpha/Kconfig: default n if ALPHA_EV5 || ALPHA_EV56 || (ALPHA_EV4 && !ALPHA_LCA)
arch/alpha/Kconfig: default n if !ALPHA_SRM && !ALPHA_GENERIC

I've sent similar patch in 2016, my version won't complain about these.

Hi again.
https://lore.kernel.org/lkml/1461259011.1918.23.camel@perches.com/
I would prefer a generic solution that also handles the
quoted use.
$ git grep -P 'default\s*\"[ynm]"' -- '*/Kconfig*'
arch/mips/Kconfig: default "y"
arch/mips/Kconfig: default "y"
arch/mips/Kconfig: default "y"
arch/mips/Kconfig: default "y"
arch/mips/cavium-octeon/Kconfig: default "n"
arch/mips/cavium-octeon/Kconfig: default "y"
arch/mips/cavium-octeon/Kconfig: default "y"
arch/mips/cavium-octeon/Kconfig: default "y"
arch/mips/cavium-octeon/Kconfig: default "y"
arch/mips/cavium-octeon/Kconfig: default "y"
arch/mips/cavium-octeon/Kconfig: default "y"
arch/powerpc/Kconfig: default "y" if PPC_POWERNV
arch/powerpc/Kconfig: default "y" if PPC_POWERNV
arch/powerpc/Kconfig: default "n"
drivers/auxdisplay/Kconfig: default "n"
drivers/crypto/Kconfig: default "m"
drivers/rapidio/devices/Kconfig: default "n"
or maybe 2 separate patches.
And the "default y" case and probably the
"default \!?EXPERT" is or should be generally
discouraged. Especially for drivers.

Thanks for your comment, perhaps we can just deal with the "default n$"
case?
