Convert more 'alloc_obj' cases to default GFP_KERNEL arguments

2026-02-22T04:03:00+00:00

This converts some of the visually simpler cases that have been split over multiple lines. I only did the ones that are easy to verify the resulting diff by having just that final GFP_KERNEL argument on the next line. Somebody should probably do a proper coccinelle script for this, but for me the trivial script actually resulted in an assertion failure in the middle of the script. I probably had made it a bit _too_ trivial. So after fighting that far a while I decided to just do some of the syntactically simpler cases with variations of the previous 'sed' scripts. The more syntactically complex multi-line cases would mostly really want whitespace cleanup anyway. Signed-off-by: Linus Torvalds

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

clk: tegra: tegra124-emc: fix device leak on set_rate()

Make sure to drop the reference taken when looking up the EMC device and its driver data on first set_rate(). Note that holding a reference to a device does not prevent its driver data from going away so there is no point in keeping the reference.

clk: tegra30: Add CSI pad clock gates

2026-01-17T00:33:18+00:00

Tegra30 has CSI pad bits in both PLLD and PLLD2 clocks that are required for the correct work of the CSI block. Add CSI pad A and pad B clock gates with PLLD/PLLD2 parents, respectively. Add a plld2 spinlock, like one plld uses, to prevent simultaneous access since both the PLLDx and CSIx_PAD clocks use the same registers Signed-off-by: Svyatoslav Ryhel Reviewed-by: Mikko Perttunen Tested-by: Luca Ceresoli # tegra20, parallel camera Signed-off-by: Thierry Reding

clk: tegra: Set CSUS as vi_sensor's gate for Tegra20, Tegra30 and Tegra114

2026-01-17T00:32:18+00:00

The CSUS clock is a clock gate for the output clock signal primarily sourced from the VI_SENSOR clock. This clock signal is used as an input MCLK clock for cameras. Unlike later Tegra SoCs, the Tegra 20 can change its CSUS parent, which is why csus_mux is added in a similar way to how CDEV1 and CDEV2 are handled.

clk: tegra: Adjust callbacks in tegra_clock_pm

2026-01-17T00:13:24+00:00

System suspend and resume callbacks run after the core has bumped up the runtime PM usage counters of all devices, so these callbacks need not worry about runtime PM reference counting. Accordingly, to eliminate useless overhead related to runtime PM usage counter manipulation, set the suspend callback pointer in tegra_clock_pm to a wrapper around pm_runtime_resume() called tegra_clock_suspend() and do not set the resume callback in it at all. This will also facilitate a planned change of the pm_runtime_put() return type to void in the future. Signed-off-by: Rafael J.
