The commit de9e33bdfa22 ("serial: 8250_dw: Improve clock rate setting") obviously tries to cure symptoms, and not a root cause. The root cause is the non-flexible rate calculation inside the corresponding clock driver. What we need is to provide maximum UART divisor value to the clock driver to allow it do the job transparently to the caller. Since from the initial commit message I have got no clue which clock driver actually needs to be amended, I leave this exercise to the people who know better the case. Moreover, it seems [1] the fix introduced a regression. And possible even one more [2]. Taking above, revert the commit de9e33bdfa22 for now.

Currently we register the pass-through serio port when we probe the F03 RMI function, and then, in sensor configure phase, we unmask interrupts. Unfortunately this is too late, as other drivers are free probe devices attached to the serio port as soon as it is probed. Because interrupts are masked, the IO times out, which may result in not being able to detect trackpoints on the pass-through port. To fix the issue we implement open() and close() methods for the pass-through serio port and unmask interrupts from there. We also move creation of the pass-through port form probe to configure stage, as RMI driver does not enable transport interrupt until all functions are probed (we should change this, but this is a separate topic). We also try to clear the pending data before unmasking interrupts, because some devices like to spam the system with multiple 0xaa 0x00 announcements, which may interfere with us trying to query ID of the device.

By default, watermark is set to '1'. Watermark is used to fine tune cyclic dma buffer period.

When a thread that uses epoll explicitly exits using BINDER_THREAD_EXIT, the waitqueue is freed, but it is never removed from the corresponding epoll data structure.

Some distributions have turned on the reset attack mitigation feature, which is designed to force the platform to clear the contents of RAM if the machine is shut down uncleanly. However, in order for the platform to be able to determine whether the shutdown was clean or not, userspace has to be configured to clear the MemoryOverwriteRequest flag on shutdown - otherwise the firmware will end up clearing RAM on every reboot, which is unnecessarily time consuming.

Quoting Hans: If we return 1 from our post_reset handler, then our disconnect handler will be called immediately afterwards. Since pre_reset blocks all scsi requests our disconnect handler will then hang in the scsi_remove_host call. This is esp. bad because our disconnect handler hanging for ever also stops the USB subsys from enumerating any new USB devices, causes commands like lsusb to hang, etc. In practice this happens when unplugging some uas devices because the hub code may see the device as needing a warm-reset and calls usb_reset_device before seeing the disconnect. In this case uas_configure_endpoints fails with -ENODEV. We do not want to print an error for this, so this commit also silences the shost_printk for -ENODEV. ENDQUOTE However, if we do that we better drop any unconditional execution and report to the SCSI subsystem that we have undergone a reset but we are not operational now.

According to drivers/usb/serial/io_edgeport.c, the driver may sleep under a spinlock. The function call path is: edge_bulk_in_callback (acquire the spinlock) process_rcvd_data process_rcvd_status change_port_settings send_iosp_ext_cmd write_cmd_usb usb_kill_urb --> may sleep To fix it, the redundant usb_kill_urb() is removed from the error path after usb_submit_urb() fails.

Upon usb composition switch there is possibility of ep0 file release happening after gadget driver bind. In case of composition switch from adb to a non-adb composition gadget will never gets bound again resulting into failure of usb device enumeration. Fix this issue by checking FFS_FL_BOUND flag and avoid extra gadget driver unbind if it is already done as part of composition switch.
