This file is not used since commit 72f045d19f25 ("riscv: Fixup difference with defconfig"), where it was replaced by the 32-bit.config fragment. Delete the old file to avoid any confusion.

2023-07-30arch/*/configs/*defconfig: Replace AUTOFS4_FS by AUTOFS_FSSven Joachim1-1/+1
Commit a2225d931f75 ("autofs: remove left-over autofs4 stubs") promised the removal of the fs/autofs/Kconfig fragment for AUTOFS4_FS within a couple of releases, but five years later this still has not happened yet, and AUTOFS4_FS is still enabled in 63 defconfigs. Get rid of it mechanically: git grep -l CONFIG_AUTOFS4_FS -- '*defconfig' | xargs sed -i 's/AUTOFS4_FS/AUTOFS_FS/' Also just remove the AUTOFS4_FS config option stub. Anybody who hasn't regenerated their config file in the last five years will need to just get the new name right when they do.
