memory: brcmstb_dpfe: Fix memory leak

2020-11-05T10:51:53Z

commit 4da1edcf8f226d53c02c6b0e3077d581115b30d0 upstream. In brcmstb_dpfe_download_firmware(), memory is allocated to variable fw by firmware_request_nowarn(), but never released. Fix up to release fw on all return paths.

memory: tegra: Remove GPU from DRM IOMMU group

2020-11-05T10:51:53Z

commit ea90f66f2a8629dde07328df0b8314aae5e54a47 upstream. 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.

memory: emif: Remove bogus debugfs error handling

2020-11-05T10:51:28Z

[ Upstream commit fd22781648080cc400772b3c68aa6b059d2d5420 ] 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.

memory: brcmstb_dpfe: fix array index out of bounds

2020-10-29T09:12:01Z

[ Upstream commit f42ae4bbf94c15aa720afb9d176ecbfe140d792e ] 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.
