I guess you just did copy&paste. "u8 uc[2];" part should be before
statement as C90.
I.e.
if (escape && (*ip == ':')) {
u8 uc[2];
if (i > len - 5)
return -EINVAL;
if (hex2bin(uc, ip + 1, 2) < 0)
return -EINVAL;
*(wchar_t *)op = uc[0] << 8 | uc[1];
op += 2;
ip += 5;
i += 5;
} else {
This should be work?
Thanks.
