Okay then I suggest to investigate what causes the ->msgs to be NULL and
fix that. When the transfer function is called we expect there to be
something to be sent out so this should not happen.
Does you kernel include commit 301c8f5c32c8 ("i2c: designware: Fix
handling of real but unexpected device interrupts")? Vanilla kernels
after v6.1 have it and also linux-stable v5.15.75 and after.
I'm asking since issue sounds similar and wanted to clarify the kernel
version you are using.
