Pull kvm fixes from Paolo Bonzini:
"ARM:
- Fix another set of FP/SIMD/SVE bugs affecting NV, and plugging some
missing synchronisation
- A small fix for the irqbypass hook fixes, tightening the check and
ensuring that we only deal with MSI for both the old and the new
route entry
- Rework the way the shadow LRs are addressed in a nesting
configuration, plugging an embarrassing bug as well as simplifying
the whole process
- Add yet another fix for the dreaded arch_timer_edge_cases selftest
RISC-V:
- Fix the size parameter check in SBI SFENCE calls
- Don't treat SBI HFENCE calls as NOPs
x86 TDX:
- Complete API for handling complex TDVMCALLs in userspace.
This was delayed because the spec lacked a way for userspace to
deny supporting these calls; the new exit code is now approved"

If spacemit_i2c_xfer_msg() times out waiting for a message transfer to
complete, or if the hardware reports an error, it returns a negative
error code (-ETIMEDOUT, -EAGAIN, -ENXIO. or -EIO).
The sole caller of spacemit_i2c_xfer_msg() is spacemit_i2c_xfer(),
which is the i2c_algorithm->xfer callback function. It currently
does not save the value returned by spacemit_i2c_xfer_msg().
The result is that transfer errors go unreported, and a caller
has no indication anything is wrong.
When this code was out for review, the return value *was* checked
in early versions. But for some reason, that assignment got dropped
between versions 5 and 6 of the series, perhaps related to reworking
the code to merge spacemit_i2c_xfer_core() into spacemit_i2c_xfer().
Simply assigning the value returned to "ret" fixes the problem.
