interconnect: qcom: qcm2290: Fix MASTER_SNOC_BIMC_NRT

2023-03-30T10:50:48+00:00

[ Upstream commit 633a12fda6536a1a17bcea29502e777e86a4547e ]

Due to what seems to be a copy-paste error, the _NRT master was
identical to the _RT master, which should not be the case.. Fix it
using the values available from the downstream kernel [1].

interconnect: qcom: sm8450: switch to qcom_icc_rpmh_* function

2023-03-30T10:50:48+00:00

[ Upstream commit 87e8fab1917a2b3f6e3dedfd1cdf22a1416e6676 ]

Change sm8450 interconnect driver to use generic qcom_icc_rpmh_*
functions rather than embedding a copy of thema. This also fixes an
overallocation of memory for icc_onecell_data structure.

interconnect: qcom: osm-l3: fix icc_onecell_data allocation

2023-03-30T10:50:48+00:00

[ Upstream commit f77ebdda0ee652124061c2ac42399bb6c367e729 ]

This is a struct with a trailing zero-length array of icc_node pointers
but it's allocated as if it were a single array of icc_nodes instead.

Fortunately this overallocates memory rather then allocating less memory
than required.

Fix by replacing devm_kcalloc() with devm_kzalloc() and struct_size()
macro.

interconnect: exynos: fix registration race

2023-03-22T12:38:00+00:00

commit c9e46ca612cfbb0cf890f7ae7389b742e90efe64 upstream.

The current interconnect provider registration interface is inherently
racy as nodes are not added until the after adding the provider. This
can specifically cause racing DT lookups to trigger a NULL-pointer
deference when either a NULL pointer or not fully initialised node is
returned from exynos_generic_icc_xlate().

Switch to using the new API where the provider is not registered until
after it has been fully initialised.

interconnect: exynos: fix node leak in probe PM QoS error path

2023-03-22T12:38:00+00:00

commit 3aab264875bf3c915ea2517fae1eec213e0b4987 upstream.

Make sure to add the newly allocated interconnect node to the provider
before adding the PM QoS request so that the node is freed on errors.
