2021-07-29usb: cdnsp: Fixed issue with ZLPPawel Laszczak
The condition "if (need_zero_pkt && zero_len_trb)" was always false and it caused that TRB for ZLP was not prepared. Fix causes that after preparing last TRB in TD, the driver prepares additional TD with ZLP when a ZLP is required.

2021-07-27usb: otg-fsm: Fix hrtimer list corruptionDmitry Osipenko
The HNP work can be re-scheduled while it's still in-fly. This results in re-initialization of the busy work, resetting the hrtimer's list node of the work and crashing kernel with null dereference within kernel/timer once work's timer is expired.

alloc_tty_driver was deprecated by tty_alloc_driver in commit 7f0bc6a68ed9 (TTY: pass flags to alloc_tty_driver) in 2012. I never got into eliminating alloc_tty_driver until now. So we still have two functions for allocating drivers which might be confusing. So get rid of alloc_tty_driver uses to eliminate it for good in the next patch. Note we need to switch return value checking as tty_alloc_driver uses ERR_PTR. And flags are now a parameter of tty_alloc_driver.

When a tty driver pointer is used as a return value of struct console's device() hook, don't store a semi-state into global variable which holds the tty driver. It could mean console::device() would return a bogus value. This is important esp. after the next patch where we switch from alloc_tty_driver to tty_alloc_driver. tty_alloc_driver returns ERR_PTR in case of error and that might have unexpected results as the code doesn't expect this.

2021-07-21bus: Make remove callback return voidUwe Kleine-König
The driver core ignores the return value of this callback because there is only little it can do when a device disappears. This is the final bit of a long lasting cleanup quest where several buses were converted to also return void from their remove callback. Additionally some resource leaks were fixed that were caused by drivers returning an error code in the expectation that the driver won't go away. With struct bus_type::remove returning void it's prevented that newly implemented buses return an ignored error code and so don't anticipate wrong expectations for driver authors.

2021-07-21Revert "USB: quirks: ignore remote wake-up on Fibocom L850-GL LTE modem"Vincent Palatin
This reverts commit 0bd860493f81eb2a46173f6f5e44cc38331c8dbd. While the patch was working as stated,ie preventing the L850-GL LTE modem from crashing on some U3 wake-ups due to a race condition between the host wake-up and the modem-side wake-up, when using the MBIM interface, this would force disabling the USB runtime PM on the device. The increased power consumption is significant for LTE laptops, and given that with decently recent modem firmwares, when the modem hits the bug, it automatically recovers (ie it drops from the bus, but automatically re-enumerates after less than half a second, rather than being stuck until a power cycle as it was doing with ancient firmware), for most people, the trade-off now seems in favor of re-enabling it by default. For people with access to the platform code, the bug can also be worked-around successfully by changing the USB3 LFPM polling off-time for the XHCI controller in the BIOS code.

2021-07-21usb: gadget: composite: Allow bMaxPower=0 if self-poweredJack Pham
Currently the composite driver encodes the MaxPower field of the configuration descriptor by reading the c->MaxPower of the usb_configuration only if it is non-zero, otherwise it falls back to using the value hard-coded in CONFIG_USB_GADGET_VBUS_DRAW. However, there are cases when a configuration must explicitly set bMaxPower to 0, particularly if its bmAttributes also has the Self-Powered bit set, which is a valid combination. This is specifically called out in the USB PD specification section 9.1, in which a PDUSB device "shall report zero in the bMaxPower field after negotiating a mutually agreeable Contract", and also verified by the USB Type-C Functional Test TD.4.10.2 Sink Power Precedence Test. The fix allows the c->MaxPower to be used for encoding the bMaxPower even if it is 0, if the self-powered bit is also set. An example usage of this would be for a ConfigFS gadget to be dynamically updated by userspace when the Type-C connection is determined to be operating in Power Delivery mode.
