Subject: [PATCH] pinctrl: sh-pfc: Add missing #include <linux/errno.h>
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Source files using -Exxx error codes should include <linux/errno.h>.
On ARM, this header file is included indirectly; on SuperH, it is not,
leading to "error: ‘EINVAL’ undeclared" failures when enabling
compile-testing later.
