Subject: usb: typec: Use sysfs_emit_at when concatenating the string
From: Kyle Tso <kyletso@xxxxxxxxxx>
commit 609fded3f91972ada551c141c5d04a71704f8967 upstream.
The buffer address used in sysfs_emit should be aligned to PAGE_SIZE.
Use sysfs_emit_at instead to offset the buffer.
Fixes: a7cff92f0635 ("usb: typec: USB Power Delivery helpers for ports and partners")
