Patch 1 adds a dedicated .restore callback for hibernate. Without it the S4 restore path runs the normal resume sequence and times out waiting for the HIF suspend MCU handshake. Patch 2 recovers from the same HIF resume timeout on S3: the firmware does not return the HIF_CTRL response after D3, so reset the device and report success instead of failing the resume. Both were tested on MEDIATEK MT7922 (14c3:7922) on kernel 6.12.113. v2: add the suspend resume fix; patch 1 is unchanged.
