Subject: xen: balloon: Replace sprintf() with sysfs_emit()
X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=77a834c9d9c66a13dcf2e69c4389a41fa23e6c39;p=thirdparty%2Fkernel%2Flinux.git

xen: balloon: Replace sprintf() with sysfs_emit()

Replace sprintf() calls with sysfs_emit() 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.
