2020-09-02memory: tegra: Remove GPU from DRM IOMMU groupThierry Reding
Commit 63a613fdb16c ("memory: tegra: Add gr2d and gr3d to DRM IOMMU group") added the GPU to the DRM IOMMU group, which doesn't make any sense. This causes problems when Nouveau tries to attach to the SMMU and causes it to fall back to using the DMA API. Remove the GPU from the DRM groups to restore the old behaviour. The GPU should always have its own IOMMU domain to make sure it can map buffers into contiguous chunks (for big page support) without getting in the way of mappings from the DRM group.

2020-08-27memory: emif: Remove bogus debugfs error handlingDan Carpenter
Callers are generally not supposed to check the return values from debugfs functions. Debugfs functions never return NULL so this error handling will never trigger. (Historically debugfs functions used to return a mix of NULL and error pointers but it was eventually deemed too complicated for something which wasn't intended to be used in normal situations). Delete all the error handling.

2020-08-22memory: brcmstb_dpfe: fix array index out of boundsMarkus Mayer
We would overrun the error_text array if we hit a TIMEOUT condition, because we were using the error code "ETIMEDOUT" (which is 110) as an array index. We fix the problem by correcting the array index and by providing a function to retrieve error messages rather than accessing the array directly. The function includes a bounds check that prevents the array from being overrun.

Also checkpatch complained: WARNING: Macros with flow control statements should be avoided ERROR: Macros starting with if should be enclosed by a do - while loop to avoid possible if/else logic defects Since GPMC_SET_ONE_CD_MAX macro just calls one function, it can be open coded.

2020-08-14iomap: constify ioreadX() iomem argument (as in generic implementation)Krzysztof Kozlowski
Patch series "iomap: Constify ioreadX() iomem argument", v3. The ioread8/16/32() and others have inconsistent interface among the architectures: some taking address as const, some not. It seems there is nothing really stopping all of them to take pointer to const. This patch (of 4): The ioreadX() and ioreadX_rep() helpers have inconsistent interface. On some architectures void *__iomem address argument is a pointer to const, on some not. Implementations of ioreadX() do not modify the memory under the address so they can be converted to a "const" version for const-safety and consistency among architectures.
