usb: cdnsp: Fix segmentation fault in cdns_lost_power function

2022-01-26T13:11:16+00:00

CDNSP driver read not initialized cdns->otg_v0_regs
which lead to segmentation fault. Patch fixes this issue.

usb: cdns3: Use platform_get_irq_byname() to get the interrupt

2021-12-21T07:51:57+00:00

platform_get_resource_byname(pdev, IORESOURCE_IRQ, ..) relies on static
allocation of IRQ resources in DT core code, this causes an issue
when using hierarchical interrupt domains using "interrupts" property
in the node as this bypasses the hierarchical setup and messes up the
irq chaining.

In preparation for removal of static setup of IRQ resource from DT core
code use platform_get_irq_byname().

usb: cdnsp: Fix lack of spin_lock_irqsave/spin_lock_restore

2021-12-15T22:44:31+00:00

Patch puts content of cdnsp_gadget_pullup function inside
spin_lock_irqsave and spin_lock_restore section.
This construction is required here to keep the data consistency,
otherwise some data can be changed e.g. from interrupt context.

usb: cdnsp: Fix incorrect status for control request

2021-12-13T14:23:42+00:00

Patch fixes incorrect status for control request.
Without this fix all usb_request objects were returned to upper drivers
with usb_reqest->status field set to -EINPROGRESS.

usb: cdnsp: Fix incorrect calling of cdnsp_died function

2021-12-13T14:23:19+00:00

Patch restrict calling of cdnsp_died function during removing modules
or software disconnect.
This function was called because after transition controller to HALT
state the driver starts handling the deferred interrupt.
In this case such interrupt can be simple ignored.

     sockmap

  Current release - new code bugs:

   - bpf: fix bpf_check_mod_kfunc_call for built-in modules

   - ice: fixes for TC classifier offloads
