Merge tag 'rpmsg-v6.18' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux

Pull rpmsg updates from Bjorn Andersson:

 - Clean up the dev_pm_domain integration in rpmsg core. Correct module
   aliases for the rpmsg char driver.

 - Transition Qualcomm SMD and GLINK drivers to strscpy() and fix the
   regression in legacy code for acquiring outgoing interrupts using the
   non-mailbox based mechanism.

* tag 'rpmsg-v6.18' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux:
  rpmsg: qcom_smd: Fix fallback to qcom,ipc parse
  rpmsg: Use strscpy() instead of strscpy_pad()
  rpmsg: core: Drop dev_pm_domain_detach() call
  rpmsg: char: Export alias for RPMSG ID rpmsg-raw from table
