2022-07-11regulator: max597x: Remove unused including <linux/version.h>Gravatar Jiapeng Chong 1-1/+0
The patch makes sense but these are not compile warnings. They come from scripts/checkversion.pl, which can be called by 'make versioncheck', so I suppose that something in your build system is running 'make versioncheck'. Eliminate the follow versioncheck warning: ./drivers/regulator/max597x-regulator.c: 21 linux/version.h not needed.
