This fixes a rare issue on my Surface Pro 5 (Arch Linux). Happens about every tenth boot.
log: dmesg.txt
As far as i debugged this, the module switches the mode from event to poll (see
ipts_eds1_switch_mode) thus callingipts_control_restart. During shutdown theIPTS_CMD_QUIESCE_IOcommand sometimes times out inipts_control_wait_flushreturningEAGAIN(-11).If the module tries to start again, the device is still "flushing" leading to the failure in
ipts_control_get_device_info, which obviously makes the touchscreen not working.Increasing the timeout in
ipts_control_wait_flushto 10 sec fixes this on my device, but maybe you have a nicer solution?? Alternatively we could increase themsleeptimeout inipts_control_restartbut i think this PR should be the better option.
