Subject: [PATCH] iio: light: vcnl4000: use sysfs_emit() for near_level
Date: Sun, 30 Aug 2026 14:42:36 +0900	[thread overview]
Message-ID: <20260830054237.2147950-1-donggeunyoo.kernel@gmail.com> (raw)

Use sysfs_emit() instead of sprintf() for writing to the sysfs
output buffer. sysfs_emit() is aware of the buffer's PAGE_SIZE
limit and is the preferred helper for sysfs callbacks.
