RE: [BUG] intel-quickspi: touchscreen DMA write timeout (Goodix 27C6:012D) on Lenovo YOGA Pro 16 IAH10

Generally speaking, a write timeout does not normally occur on the SPI bus. 
If it does happen, it usually indicates that there is a problem with the bus, or that the touch device has lost power. 
You can try unloading the intel_quickspi driver with rmmod, then reload it with insmod, and check the kernel log to see whether a different symptom appears.
