Hi all, After merging the regulator tree, today's linux-next build (x86_64 allmodconfig) failed like this: drivers/regulator/sy7636a-regulator.c:14:10: fatal error: linux/mfd/sy7636a.h: No such file or directory 14 | #include | ^~~~~~~~~~~~~~~~~~~~~ Caused by commit cb17820ef71e ("regulator: sy7636a: Remove requirement on sy7636a mfd") I have used the regulator tree from next-20211021 for today. -- Cheers, Stephen Rothwell
