usb: core: add quirk for Alcor Link AK9563 smartcard reader

2023-02-09T12:23:51Z

The Alcor Link AK9563 smartcard reader used on some Lenovo platforms doesn't work. If LPM is enabled the reader will provide an invalid usb config descriptor. Added quirk to disable LPM.

usb: typec: altmodes/displayport: Fix probe pin assign check

2023-02-09T12:23:39Z

While checking Pin Assignments of the port and partner during probe, we don't take into account whether the peripheral is a plug or receptacle. This manifests itself in a mode entry failure on certain docks and dongles with captive cables. For instance, the Startech.com Type-C to DP dongle (Model #CDP2DP) advertises its DP VDO as 0x405. This would fail the Pin Assignment compatibility check, despite it supporting Pin Assignment C as a UFP. Update the check to use the correct DP Pin Assign macros that take the peripheral's receptacle bit into account.

Revert "usb: gadget: u_ether: Do not make UDC parent of the net device"

2023-02-09T12:18:24Z

This reverts commit 321b59870f850a10dbb211ecd2bd87b41497ea6f. This commit broke USB networking on Ingenic SoCs and maybe elsewhere. The actual reason is unknown; and while a proper fix would be better, we're sitting at -rc7 now, so a revert is justified - and we can work on re-introducing this change for 6.3.

usb: gadget: udc: do not clear gadget driver.bus

2023-02-02T08:41:17Z

Before the commit fc274c1e9973 ("USB: gadget: Add a new bus for gadgets") gadget driver.bus was unused. For whatever reason, many UDC drivers set this field explicitly to NULL in udc_start(). With the newly added gadget bus, doing this will crash the driver during the attach. The problem was first reported, fixed and tested with OMAP UDC and g_ether. Other drivers are changed based on code analysis only.

usb: gadget: f_uac2: Fix incorrect increment of bNumEndpoints

2023-01-25T15:17:46Z

Currently connect/disconnect of USB cable calls afunc_bind and eventually increments the bNumEndpoints. Performing multiple plugin/plugout will increment bNumEndpoints incorrectly, and on the next plug-in it leads to invalid configuration of descriptor and hence enumeration fails. Fix this by resetting the value of bNumEndpoints to 1 on every afunc_bind call.

usb: gadget: f_fs: Fix unbalanced spinlock in __ffs_ep0_queue_wait

2023-01-24T17:19:39Z

__ffs_ep0_queue_wait executes holding the spinlock of &ffs->ev.waitq.lock and unlocks it after the assignments to usb_request are done. However in the code if the request is already NULL we bail out returning -EINVAL but never unlocked the spinlock. Fix this by adding spin_unlock_irq &ffs->ev.waitq.lock before returning.
