This is a note to let you know that I've just added the patch titled
usb: typec: wcove: Use LE to CPU conversion when accessing
to my usb git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git
in the usb-linus branch.
The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)
The patch will hopefully also be merged in Linus's tree for the
next -rc kernel release.
If you have any questions about this process, please let me know.

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