Subject: hwmon: (max31722) Replace sprintf() with sysfs_emit()
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=aeb651cc95e83ccf129ba9151dd22101619dea1e;p=thirdparty%2Fkernel%2Flinux.git

hwmon: (max31722) 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.
