Syzbot reported uninit value in mcs7830_bind(). The problem was in missing validation check for bytes read via usbnet_read_cmd(). usbnet_read_cmd() internally calls usb_control_msg(), that returns number of bytes read. Code should validate that requested number of bytes was actually read.

2022-01-10bnxt_en: improve firmware timeout messagingEdwin Peer4-24/+25
While it has always been possible to infer that an HWRM command was abandoned due to an unhealthy firmware status by the shortened timeout reported, this change improves the log messaging to account for this case explicitly.

2022-01-10bnxt_en: use firmware provided max timeout for messagesEdwin Peer6-12/+15
Some older devices cannot accommodate the 40 seconds timeout cap for long running commands (such as NVRAM commands) due to hardware limitations. Allow these devices to request more time for these long running commands, but print a warning, since the longer timeout may cause the hung task watchdog to trigger. In the case of a firmware update operation, this is preferable to failing outright. v2: Use bp->hwrm_cmd_max_timeout directly without the constants.

2022-01-10bnxt_en: improve VF error messages when PF is unavailableEdwin Peer3-9/+40
The current driver design relies on the PF netdev being open in order to intercept the following HWRM commands from a VF: - HWRM_FUNC_VF_CFG - HWRM_CFA_L2_FILTER_ALLOC - HWRM_PORT_PHY_QCFG (only if FW_CAP_LINK_ADMIN is not supported) If the PF is closed, then VFs are subjected to rather inscrutable error messages in response to any configuration requests involving the above command types. Recent firmware distinguishes this problem case from other errors by returning HWRM_ERR_CODE_PF_UNAVAILABLE. In most cases, the appropriate course of action is still to fail, but this can now be accomplished with the aid of more user informative log messages. For L2 filter allocations that are already asynchronous, an automatic retry seems more appropriate. v2: Delete extra newline.

2022-01-09pcmcia: fix setting of kthread task statesDominik Brodowski1-5/+3
We need to set TASK_INTERRUPTIBLE before calling kthread_should_stop(). Otherwise, kthread_stop() might see that the pccardd thread is still in TASK_RUNNING state and fail to wake it up. Additionally, we only need to set the state back to TASK_RUNNING if kthread_should_stop() breaks the loop.

For the possible failure of the platform_get_irq(), the returned irq could be error number and will finally cause the failure of the request_irq(). Consider that platform_get_irq() can now in certain cases return -EPROBE_DEFER, and the consequences of letting request_irq() effectively convert that into -EINVAL, even at probe time rather than later on. So it might be better to check just now.

The supply names of the Zinitix touchscreen were a bit confused, the new bindings rectifies this. To deal with old and new devicetrees, first check if we have "vddo" and in case that exists assume the old supply names. Else go and look for the new ones. We cannot just get the regulators since we would get an OK and a dummy regulator: we need to check explicitly for the old supply name. Use struct device *dev as a local variable instead of the I2C client since the device is what we are actually obtaining the resources from.

2022-01-09Input: zinitix - make sure the IRQ is allocated before it gets enabledNikita Travkin1-9/+9
Since irq request is the last thing in the driver probe, it happens later than the input device registration. This means that there is a small time window where if the open method is called the driver will attempt to enable not yet available irq. Fix that by moving the irq request before the input device registration.

2022-01-09Input: axp20x-pek - revert "always register interrupt handlers" changeHans de Goede1-37/+35
The power button on Cherry Trail systems with an AXP288 PMIC is connected to both the power button pin of the PMIC as well as to a power button GPIO on the Cherry Trail SoC itself. This leads to double power button event reporting which is a problem. Since reporting power button presses through the PMIC is not supported on all PMICs used on Cherry Trail systems, we want to keep the GPIO power button events, so the axp20x-pek code checks for the presence of a GPIO power button and in that case does not register its input-device. On most systems the GPIO power button also can wake-up the system from suspend, so the axp20x-pek driver would also not register its interrupt handler. But on some systems there was a bug causing wakeup by the GPIO power button handler to not work. Commit 9747070c11d6 ("Input: axp20x-pek - always register interrupt handlers") was added as a work around for this registering the axp20x-pek interrupts, but not the input-device on Cherry Trail systems. In the mean time the root-cause of the GPIO power button wakeup events not working has been found and fixed by the "pinctrl: cherryview: Do not allow the same interrupt line to be used by 2 pins" patch, so this is no longer necessary. This reverts the workaround going back to only registering the interrupt handlers on systems where we also register the input-device.

2022-01-09tpm: fix potential NULL pointer access in tpm_del_char_deviceLino Sanfilippo1-5/+13
Some SPI controller drivers unregister the controller in the shutdown handler (e.g. BCM2835). If such a controller is used with a TPM 2 slave chip->ops may be accessed when it is already NULL: At system shutdown the pre-shutdown handler tpm_class_shutdown() shuts down TPM 2 and sets chip->ops to NULL. Then at SPI controller unregistration tpm_tis_spi_remove() is called and eventually calls tpm_del_char_device() which tries to shut down TPM 2 again. Thereby it accesses chip->ops again: (tpm_del_char_device calls tpm_chip_start which calls tpm_clk_enable which calls chip->ops->clk_enable). Avoid the NULL pointer access by testing if chip->ops is valid and skipping the TPM 2 shutdown procedure in case it is NULL.
