Subject: crypto: omap - Use sysfs_emit in sysfs show functions
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=279b837c1f752c2f261c46a2ae6f56ce3159ecea;p=thirdparty%2Fkernel%2Flinux.git

crypto: omap - Use sysfs_emit in sysfs show functions

Replace sprintf() with sysfs_emit() in sysfs show functions.
sysfs_emit() is preferred to format sysfs output as it provides better
bounds checking.  No functional changes.
