Subject: [PATCH v12 05/10] iommu/arm-smmu-v3: Make symbols public for CONFIG_TEGRA241_CMDQV
Date: Thu, 15 Aug 2024 17:55:26 -0700	[thread overview]
Message-ID: <ce5463b8e25474c0a0aaeb93df3be2d0ee3ae3aa.1723754745.git.nicolinc@nvidia.com> (raw)
In-Reply-To: <cover.1723754745.git.nicolinc@nvidia.com>

The symbols __arm_smmu_cmdq_skip_err(), arm_smmu_init_one_queue(), and
arm_smmu_cmdq_init() need to be used by the tegra241-cmdqv compilation
unit in a following patch.

Remove the static and put prototypes in the header.
