From: Dave Martin Date: Fri, 28 Sep 2018 13:39:07 +0000 (+0100) Subject: KVM: arm64: Refactor kvm_arm_num_regs() for easier maintenance X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=7aa92cf318f8136c445c1656d291f50df189b56a;p=openwrt%2Fstaging%2Fblogic.git KVM: arm64: Refactor kvm_arm_num_regs() for easier maintenance kvm_arm_num_regs() adds together various partial register counts in a freeform sum expression, which makes it harder than necessary to read diffs that add, modify or remove a single term in the sum (which is expected to the common case under maintenance). This patch refactors the code to add the term one per line, for maximum readability.
