2021-04-22usb: dwc2: Move exit hibernation to dwc2_port_resume() functionArtur Petrosyan
This move is done to call hibernation exit handler in "dwc2_port_resume()" function when core receives port resume. Otherwise it could be confusing to exit hibernation in "dwc2_hcd_hub_control()" function but other power saving modes in "dwc2_port_resume()" function.

2021-04-22usb: dwc2: Clear GINTSTS_RESTOREDONE bit after restore is generated.Artur Petrosyan
When hibernation exit is performed the dwc2_hib_restore_common() function is called. In that function we wait until GINTSTS_RESTOREDONE bit is set. However, after the setting of that bit we get a lot of (dwc2_hsotg_irq:) interrupts which indicates that (GINTSTS.RstrDoneInt) restore done interrupt is asserted. To avoid restore done interrupt storm after restore is generated clear GINTSTS_RESTOREDONE bit in GINTSTS register.

2021-04-22usb: dwc2: Clear fifo_map when resetting core.Artur Petrosyan
Switching from device mode to host mode by disconnecting device cable core enters and exits form hibernation. However, the fifo map remains not cleared. It results to a WARNING (WARNING: CPU: 5 PID: 0 at drivers/usb/dwc2/ gadget.c:307 dwc2_hsotg_init_fifo+0x12/0x152 [dwc2]) if in host mode we disconnect the micro a to b host cable. Because core reset occurs. To avoid the WARNING, fifo_map should be cleared in dwc2_core_reset() function by taking into account configs. fifo_map must be cleared only if driver is configured in "CONFIG_USB_DWC2_PERIPHERAL" or "CONFIG_USB_DWC2_DUAL_ROLE" mode. - Added "static inline void dwc2_clear_fifo_map()" helper function to clear fifo_map with peripheral or dual role mode. - Added a dummy version of "dwc2_clear_fifo_map()" helper for host-only mode.

2021-04-22usb: dwc2: Allow exiting hibernation from gpwrdn rst detectArtur Petrosyan
When device cable is disconnected core receives suspend interrupt and enters hibernation. After entering into hibernation GPWRDN_RST_DET and GPWRDN_STS_CHGINT interrupts are asserted. Allowed exit from gadget hibernation from GPWRDN_RST_DET by checking only linestate. Changed the return type of "dwc2_handle_gpwrdn_intr()" function from void to int because exit from hibernation functions have a return value.

2021-04-22usb: dwc2: Fix hibernation between host and device modes.Artur Petrosyan
When core is in hibernation in host mode and a device cable was connected then driver exited from device hibernation. However, registers saved for host mode and when exited from device hibernation register restore would be done for device register which was wrong because there was no device registers stored to restore. - Added dwc_handle_gpwrdn_disc_det() function which handles gpwrdn disconnect detect flow and exits hibernation without restoring the registers. - Updated exiting from hibernation in GPWRDN_STS_CHGINT with calling dwc_handle_gpwrdn_disc_det() function. Here no register is restored which is the solution described above.

2021-04-22usb: gadget: dummy_hcd: fix gpf in gadget_setupAnirudh Rayabharam
Fix a general protection fault reported by syzbot due to a race between gadget_setup() and gadget_unbind() in raw_gadget. The gadget core is supposed to guarantee that there won't be any more callbacks to the gadget driver once the driver's unbind routine is called. That guarantee is enforced in usb_gadget_remove_driver as follows: usb_gadget_disconnect(udc->gadget); if (udc->gadget->irq) synchronize_irq(udc->gadget->irq); udc->driver->unbind(udc->gadget); usb_gadget_udc_stop(udc); usb_gadget_disconnect turns off the pullup resistor, telling the host that the gadget is no longer connected and preventing the transmission of any more USB packets. Any packets that have already been received are sure to processed by the UDC driver's interrupt handler by the time synchronize_irq returns. But this doesn't work with dummy_hcd, because dummy_hcd doesn't use interrupts; it uses a timer instead. It does have code to emulate the effect of synchronize_irq, but that code doesn't get invoked at the right time -- it currently runs in usb_gadget_udc_stop, after the unbind callback instead of before. Indeed, there's no way for usb_gadget_remove_driver to invoke this code before the unbind callback. To fix this, move the synchronize_irq() emulation code to dummy_pullup so that it runs before unbind. Also, add a comment explaining why it is necessary to have it there.

2021-04-22staging: rtl8723bs: replace DBG_871X_LEVEL logs with netdev_*()Fabio Aiuto
Replace DBG_871X_LEVEL logs with netdev_*() functions where possible (i.e. where a pointer to netdev is easily available). This is not possible in correspondance of redundant log in module initialization. So remove those ones. DBG_871X_LEVEL macro wraps a raw printk call which is not recommended in a device driver context, prefer using netdev_*() log functions. The remove/replace operation has been done with the following semantic patch script: @@ expression list args; identifier padapter; identifier func; symbol _drv_always_, _drv_info_, _drv_warning_; symbol _drv_err_, _drv_emerg_; @@ func(..., struct adapter *padapter, ...) { <...

2021-04-22arm64: dts: allwinner: Revert SD card CD GPIO for Pine64-LTSAndre Przywara
Commit 941432d00768 ("arm64: dts: allwinner: Drop non-removable from SoPine/LTS SD card") enabled the card detect GPIO for the SOPine module, along the way with the Pine64-LTS, which share the same base .dtsi. This was based on the observation that the Pine64-LTS has as "push-push" SD card socket, and that the schematic mentions the card detect GPIO. After having received two reports about failing SD card access with that patch, some more research and polls on that subject revealed that there are at least two different versions of the Pine64-LTS out there: - On some boards (including mine) the card detect pin is "stuck" at high, regardless of an microSD card being inserted or not. - On other boards the card-detect is working, but is active-high, by virtue of an explicit inverter circuit, as shown in the schematic. To cover all versions of the board out there, and don't take any chances, let's revert the introduction of the active-low CD GPIO, but let's use the broken-cd property for the Pine64-LTS this time. That should avoid regressions and should work for everyone, even allowing SD card changes now. The SOPine card detect has proven to be working, so let's keep that GPIO in place.

2021-04-22fsverity: relax build time dependency on CRYPTO_SHA256Ard Biesheuvel
CONFIG_CRYPTO_SHA256 denotes the generic C implementation of the SHA-256 shash algorithm, which is selected as the default crypto shash provider for fsverity. However, fsverity has no strict link time dependency, and the same shash could be exposed by an optimized implementation, and arm64 has a number of those (scalar, NEON-based and one based on special crypto instructions). In such cases, it makes little sense to require that the generic C implementation is incorporated as well, given that it will never be called. To address this, relax the 'select' clause to 'imply' so that the generic driver can be omitted from the build if desired.

2021-04-22fscrypt: relax Kconfig dependencies for crypto API algorithmsArd Biesheuvel
Even if FS encryption has strict functional dependencies on various crypto algorithms and chaining modes. those dependencies could potentially be satisified by other implementations than the generic ones, and no link time dependency exists on the 'depends on' claused defined by CONFIG_FS_ENCRYPTION_ALGS. So let's relax these clauses to 'imply', so that the default behavior is still to pull in those generic algorithms, but in a way that permits them to be disabled again in Kconfig.
