This series contains some cleanups applicable to the SVE KVM support
patches merged into kvmarm/next. These arose from Andrew Jones'
review.
Apart from some minor changes to error codes and checking, these are
mostly cosmetic / sytlistic changes only.
The patches are based on
git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm.git next
5d8d4af24460 ("arm64: KVM: Fix system register enumeration")
This series in git:
git://linux-arm.org/linux-dm.git sve-kvm-fixes/v2/head
http://linux-arm.org/git?p=linux-dm.git;a=shortlog;h=refs/heads/sve-kvm-fixes/v2/head
Tested with qemu and kvmtool on ThunderX2, and with kvmtool on the Arm
Fast model (to exercise SVE support).
Some additional manual testing was done to exercise the updated error
behaviours when accessing the SVE registers via ioctl.
