ifying the "Subject" line. The Subject line should ideally be no
more than about 70 characters, and just needs to summarize. So
go with something like:
[PATCH] drivers: hv: Fix whitespace errors
Or:
[PATCH] drivers: hv: Fix whitespace errors from checkpatch
The "drivers: hv:"
Update drivers/hv/Kconfig so CONFIG_HYPERV can be selected on
ARM64, causing the Hyper-V specific code to be built.
