[PATCH] kconfig: update to Linux 5.9-rc2

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The previous sync was Linux 5.7-rc2. Resync scripts/kconfig/ and
scripts/Kconfig.include with Linux 5.9-rc2.

Highlights:

 - fix and improve 'make xconfig'

 - remove '---help---' keyword

 - forbid nested 'choice' blocks
