From mboxrd@z Thu Jan 1 00:00:00 1970 From: sricharan@codeaurora.org (Sricharan R) Date: Tue, 23 Jun 2015 17:37:26 +0530 Subject: [PATCH] iommu/arm-smmu: Fix bug in ARM_SMMU_FEAT_TRANS_OPS condition check Message-ID: <1435061246-14690-1-git-send-email-sricharan@codeaurora.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Patch 'fix ARM_SMMU_FEAT_TRANS_OPS condition' changed the check for ARM_SMMU_FEAT_TRANS_OPS to be based on presence of stage1 check, but used (id & ID0_ATOSNS) instead of !(id & ID0_ATOSNS). Fix it here.
