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

2026-04-02T07:37:45Z

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

usb: dwc3: Add optional VBUS regulator support to SpacemiT K1

2026-03-30T14:51:21Z

Some SpacemiT K1 boards (like OrangePi R2S) provide USB VBUS through a controllable regulator. Add support for the optional vbus-supply property so the regulator can be properly managed in host mode instead of left always-on. Note that this doesn't apply to USB Hub downstream ports with different VBUS supplies. The enabled and disabled actions of the regulator are handled automatically by devm_regulator_get_enable_optional().

usb: dwc3: imx: avoid calling imx suspend/resume callbacks twice

2026-03-18T15:22:18Z

If a runtime suspend is executed followed by a system suspend, the driver may invoke dwc3_imx_suspend() twice, which causes enable_irq() to be called twice as well. This leads to an unbalanced IRQ state and may trigger warnings or malfunction. Prevent this by checking the pm_suspended flag before running the imx suspend/resume path.

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

2026-03-18T15:18:22Z

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.

usb: dwc3: gadget: use explicit 0 for success in __dwc3_gadget_kick_transfer()

2026-03-11T14:23:43Z

Smatch warns that __dwc3_gadget_kick_transfer() might be missing an error code when returning 'ret' at line 1691. While 'ret' is guaranteed to be 0 at this point, returning an explicit 0 improves readability by removing a level of indirection and clarifies the intent that this is a successful "no-op" path. This change also silences the Smatch warning.
