SPI-HID driver fails intermittently

[qzed]

The spi_hid driver fails intermittently, preventing touch input from working. I am not sure whether this happens during probe or device open. As a workaround, the module or driver can be reloaded/re-bound manually (multiple times, if necessary).

Maybe this helps debugging the issue:
