net: qrtr: resend HELLO on MHI resume

2026-09-20T18:21:10+00:00

Since the MHI HELLO exchange was relocated, it is sent only at device registration. During a suspend-resume cycle, the firmware in WiFi cards such as WCN7850 indefinitely waits for another HELLO, triggering: ath12k_wifi7_pci 0004:01:00.0: timeout while waiting for restart complete ath12k_wifi7_pci 0004:01:00.0: failed to resume core: -110 Fix this by triggering the handshake from resume_early in the MHI transport. Validated on Qualcomm X1E-801800 on Lenovo Slim 7x across 10 suspend-resume cycles.
