Subject: [PATCH v5 13/19] KVM: Simplify kvm_free_memslot() and all its descendents
Date: Tue, 21 Jan 2020 14:31:51 -0800
Message-ID: <20200121223157.15263-14-sean.j.christopherson@intel.com> (raw)
In-Reply-To: <20200121223157.15263-1-sean.j.christopherson@intel.com>

Now that all callers of kvm_free_memslot() pass NULL for @dont, remove
the param from the top-level routine and all arch's implementations.

No functional change intended.

Tested-by: Christoffer Dall <christoffer.dall@arm.com>
