Subject: [GIT PULL] I3C changes for 6.15

Hello Linus,

Here is the i3c subsystem pull request for 6.15. The silvaco driver gets
support for the integration of the IP in the Nuvoton npcm845 SoC. There
is also a fix for a possible NULL pointer dereference that can happen
with early IBIs.

The following changes since commit 2014c95afecee3e76ca4a56956a936e23283f05b:
