Subject: [PATCH v2 06/15] spi: Use sysfs_emit() to instead of s*printf()

From: Andy Shevchenko <[email-masked]>
Date: Mon, 10 Jul 2023 18:49:23 +0300

Follow the advice of the Documentation/filesystems/sysfs.rst and show()
should only use sysfs_emit() or sysfs_emit_at() when formatting the
value to be returned to user space.
