Convert 'alloc_obj' family to use the new default GFP_KERNEL argument

This was done entirely with mindless brute force, using git grep -l '\

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook

soc/tegra: pmc: Add PMC contextual functions

2026-01-18T07:48:30+00:00

Add implementations that take as argument a struct tegra_pmc * for most public APIs, as well as a function to obtain the PMC for any given device. This will allow transitioning away users from relying on a global variable storing the PMC context. Signed-off-by: Thierry Reding

soc/tegra: pmc: Do not rely on global variable

2026-01-18T07:48:30+00:00

The reset action for changing the suspend mode back on failure can take a context-specific data argument that can be set to the PMC context in order to avoid relying on a global variable. Signed-off-by: Thierry Reding

soc/tegra: pmc: Use driver-private data

2026-01-18T07:48:30+00:00

Instead of relying on a global variable for the PMC context, use the driver-private data for sysfs attributes. Signed-off-by: Thierry Reding

soc/tegra: pmc: Use PMC context embedded in powergates

2026-01-18T07:48:29+00:00

The powergates exposed by the PMC have a pointer to the PMC context embedded. Use that embedded reference instead of relying on a global variable. For the core power domain a new structure needs to be introduced to wrap the generic PM domain and store the PMC context. Signed-off-by: Thierry Reding

soc/tegra: pmc: Pass PMC context as debugfs data

2026-01-18T07:48:29+00:00

Each debugfs file can have private data associated with it. Use this to pass the PMC context instead of relying on a global variable. Signed-off-by: Thierry Reding

soc/tegra: pmc: Pass PMC context via sys-off callback data

2026-01-18T07:48:29+00:00

To avoid relying on global variables, use the sys-off callback data to store a reference to the PMC context structure. Signed-off-by: Thierry Reding

soc/tegra: pmc: Embed reboot notifier in PMC context

2026-01-18T07:48:29+00:00

Instead of relying on a global variable to track the PMC context, embed the reboot notifier into the PMC context so that the latter can be resolved using container_of(). Signed-off-by: Thierry Reding

soc/tegra: pmc: Store PMC context in clocks

2026-01-18T07:48:29+00:00

Clocks exposed by the PMC need to reference the PMC context for register programming. Store a reference to the context in the data structure for each clock to avoid the need for a global variable. Signed-off-by: Thierry Reding
