I suspect the issue is that it's not primarily a software engineer who

Currently we are assuming a one to one mapping between dmabuf and handle

But that is not always true, since we would create extra handles for the
GEM obj in cases like gem_open() and getfb{,2}().

If the previous thing cat'ing $debugfs/rd left the FIFO full, then
subsequent open could deadlock in rd_write() (because open is blocked,
not giving a chance for read() to consume any data in the FIFO). Also
it is generally a good idea to clear out old data from the FIFO.

Don't directly restart the hangcheck timer from the timer handler, but
instead start it after the recover_worker replays remaining jobs.
If the kthread is blocked for other reasons, there is no point to

Fix i2c transfers using GPI DMA mode for all message types that do not set
the I2C_M_DMA_SAFE flag (e.g. SMBus "read byte").
In this case a bounce buffer is returned by i2c_get_dma_safe_msg_buf(),
and it has to synced back to the message after the transfer is done.
