Subject: usb: typec: Fix fast_role_swap_current show function
From: Pavan Holla <pholla@xxxxxxxxxxxx>
commit 92c9c3baad6b1fd584fbabeaa4756f9b77926cb5 upstream.
The current implementation mistakenly performs a & operation on
the output of sysfs_emit. This patch performs the & operation before
calling sysfs_emit.
Fixes: 662a60102c12 ("usb: typec: Separate USB Power Delivery from USB Type-C")
