Subject: usb: typec: wcove: Use LE to CPU conversion when accessing msg->header

From: Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx>

commit d5ab95da2a41567440097c277c5771ad13928dad upstream.

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.

Fixes: ae8a2ca8a221 ("usb: typec: Group all TCPCI/TCPM code together")
Fixes: 3c4fb9f16921 ("usb: typec: wcove: start using tcpm for USB PD support")
