Subject: x86/platform/olpc: Replace strcpy() with strscpy() in xo15_sci_add()
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c957072d44a735ebbe8385fc3511a4f5e6ccea93;p=thirdparty%2Fkernel%2Flinux.git

x86/platform/olpc: Replace strcpy() with strscpy() in xo15_sci_add()

strcpy() has been deprecated¹ because it performs no bounds checking on the
destination buffer, which can lead to buffer overflows. Use the safer
strscpy() instead.
