As LKP noticed the Sparse is not happy about strict type handling: .../typec/tcpm/wcove.c:380:50: sparse: expected unsigned short [usertype] header .../typec/tcpm/wcove.c:380:50: sparse: got restricted __le16 const [usertype] header Fix this by switching to use pd_header_cnt_le() instead of pd_header_cnt() in the affected code.
