Subject: thermal: intel: int340x: Replace sprintf() with sysfs_emit()
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=347d92a79585c6c54be635be9e667384d2685c5c;p=thirdparty%2Fkernel%2Flinux.git

thermal: intel: int340x: Replace sprintf() with sysfs_emit()

Replace sprintf() calls with sysfs_emit() in sysfs "show" functions to
follow current kernel coding standards.

sysfs_emit() is the preferred method for formatting sysfs output as it
provides better bounds checking and is more secure.
