Subject: tools/nolibc: Rename the 'errnum' parameter to strerror()
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=c0a08eb87f60daec1c1549c067945abfee711f86;p=thirdparty%2Fkernel%2Flinux.git

tools/nolibc: Rename the 'errnum' parameter to strerror()

Change the parameter variable name from 'errno' to 'errnum'.
Matches any documentation and avoids any issues that might happen
if errno is actually a #define (which is not uncommon).
