usb: dwc3: imx8mp: fix memory leak on probe failure path

2026-04-02T07:37:45+00:00

When platform_get_drvdata() returns NULL and probe defers, the error path jumps to the 'depopulate' label, skipping put_device() for the reference acquired by of_find_device_by_node(). This extra reference prevents the child platform device from being freed when of_platform_depopulate() is called, resulting in memory leaks reported by kmemleak: unreferenced object 0xffff0000c92c1480 (size 64): comm "kworker/u16:2", pid 50, jiffies 4294895789 backtrace (crc 49d507d0): kmemleak_alloc+0x34/0x40 __kmalloc_noprof+0x430/0x670 of_device_alloc+0xec/0x26c of_platform_device_create_pdata+0x60/0x1f0 of_platform_bus_create+0x290/0x610 of_platform_populate+0x74/0x118 dwc3_imx8mp_probe+0x228/0x734 Fixes: 86767625f525 ("usb: dwc3: imx8mp: disable auto suspend for host role") Signed-off-by: Xiaolei Wang Acked-by: Thinh Nguyen Link: https://patch.msgid.link/20260401134938.686748-1-xiaolei.wang@windriver.com Signed-off-by: Greg Kroah-Hartman

dwc3: google: Fix PM domain leak in dwc3_google_probe()

2026-03-18T15:18:22+00:00

When syscon_regmap_lookup_by_phandle_args() fails, the function was returning directly without cleaning up the power domain initialized earlier by dwc3_google_pm_domain_init(). Fix by jumping to err_deinit_pdom to properly clean up resources.

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

usb: dwc3: gadget: Move vbus draw to workqueue context

2026-02-05T16:13:48+00:00

Currently dwc3_gadget_vbus_draw() can be called from atomic context, which in turn invokes power-supply-core APIs. And some these PMIC APIs have operations that may sleep, leading to kernel panic. Fix this by moving the vbus_draw into a workqueue context.

usb: dwc3: Log dwc3 address in traces

2026-01-27T14:52:45+00:00

When multiple DWC3 controllers are being used, trace events from different instances get mixed up making debugging difficult as there's no way to distinguish which instance generated the trace. Use the register base address of dwc3 controller and append it to trace events, so that the source instance is clearly identifiable. Example trace output, before -> dwc3_event: event (00000101): Reset [U0] after -> dwc3_event: 0x000000000a600000: event (00000101): Reset [U0] Signed-off-by: Prashanth K Acked-by: Thinh Nguyen Link: https://patch.msgid.link/20260122105000.4126769-1-prashanth.k@oss.qualcomm.com Signed-off-by: Greg Kroah-Hartman

usb: dwc3: google: Remove redundant dev_err()

2026-01-23T16:16:05+00:00

The platform_get_irq_byname() function already prints an error message internally upon failure using dev_err_probe(). Therefore, the explicit dev_err() is redundant and results in duplicate error logs. Remove the redundant dev_err() call to clean up the error path.

usb: dwc3: Add dwc pointer to dwc3_readl/writel

2026-01-16T12:47:07+00:00

Use dwc pointer in dwc3_readl() dwc3_writel() instead of passing the dwc->regs. This would help us access the dwc structure and log the base address in traces. There's no functional changes in this patch, just refactoring existing APIs.
