Subject: m68knommu: Replace deprecated strcpy with strscpy in init_ucsimm
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a16ac6ca46d62bcbcbd7b01be0ef03fb39530d7b;p=thirdparty%2Flinux.git

m68knommu: Replace deprecated strcpy with strscpy in init_ucsimm

strcpy() has been deprecated [1] because it performs no bounds checking
on the destination buffer, which can lead to buffer overflows. Replace
it with the safer strscpy().
