commit 9982fe275ba4ee1a749b6dde5602a5a79e42b543 Author: Roger Pau Monné <roger.pau@xxxxxxxxxx> AuthorDate: Thu Sep 29 14:41:13 2022 +0200 Commit: Jan Beulich <jbeulich@xxxxxxxx> CommitDate: Thu Sep 29 14:41:13 2022 +0200 arm/vgic: drop const attribute from gic_iomem_deny_access() While correct from a code point of view, the usage of the const attribute for the domain parameter of gic_iomem_deny_access() is at least partially bogus. Contents of the domain structure (the iomem rangeset) is modified by the function. Such modifications succeed because right now the iomem rangeset is allocated separately from struct domain, and hence is not subject to the constness of struct domain. Amend this by dropping the const attribute from the function parameter. This is required by further changes that will convert iomem_{permit,deny}_access into a function.
