Merge tag 'char-misc-5.18-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc
Pull char/misc driver fixes from Greg KH: "Here are two small driver fixes for 5.18-rc7 that resolve reported problems: - slimbus driver irq bugfix - interconnect sync state bugfix Both of these have been in linux-next with no reported problems" * tag 'char-misc-5.18-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: slimbus: qcom: Fix IRQ check in qcom_slim_probe interconnect: Restore sync state by ignoring ipa-virt in provider count
