For different reasons i2c transaction may fail or report id in the
message may be wrong. Avoid closing the frame in this case as it will
result in all contacts being dropped, indicating that nothing is
touching the screen anymore, while usually it is not the case.

0204485c5a1e2de00acfd83c3931bd9dc6493c64 | Analyze and fix the following issue in the Linux kernel code: dt-bindings: fsl-qdma: allow compatible string fallback to fsl,ls1021a-qdma | Problem Details:
The IP of QDMA ls1028/ls1043/ls1046/ is same as ls1021. So allow compatible
string fallback to fsl,ls1021a-qdma.
The difference is that ls1021a-qdma have 3 irqs, and other have 5 irqs.
Fix below CHECK_DTB warning.

Use the late-read buffer in the CS35L56 SoundWire interface to
read OTP memory.
The OTP memory has a longer access latency than chip registers
