Subject: hwmon: (ads7828) Replace sprintf() with sysfs_emit()
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=5de81d9b9ff6a26f3f7e75f0aa93b26cc81acd86;p=thirdparty%2Fkernel%2Flinux.git

hwmon: (ads7828) Replace sprintf() with sysfs_emit()

Replace sprintf() with sysfs_emit() when writing to sysfs buffers.

sysfs_emit() performs proper bounds checking and is the preferred
helper for sysfs output.

No functional change intended.
