Subject: [PATCH 5.9 066/152] xtensa: uaccess: Add missing __user to strncpy_from_user() prototype

From: Laurent Pinchart <laurent.pinchart@...asonboard.com>

[ Upstream commit dc293f2106903ab9c24e9cea18c276e32c394c33 ]

When adding __user annotations in commit 2adf5352a34a, the
strncpy_from_user() function declaration for the
CONFIG_GENERIC_STRNCPY_FROM_USER case was missed. Fix it.
