There is a code (because I am already in s-o-b list I just put here
the excerpts, however, I could prepare patch in standard form, if you
want to)
static s32 uuid_hex_to_bin(char *buf, s32 len)
{
s32 i;
s32 result = 0;
for (i = 0; i < len; i++) {
value = hex_to_bin(*buf++);
result *= 16;
if (value > 0)
result += value;
}
return result;
}
void uuid_uuid_from_string(IN char *pszUuid, OUT struct dsp_uuid *uuid_obj)
{
s32 j;
uuid_obj->ul_data1 = uuid_hex_to_bin(pszUuid, 8);
pszUuid += 8;
/* Step over underscore */
pszUuid++;
uuid_obj->us_data2 = (u16) uuid_hex_to_bin(pszUuid, 4);
pszUuid += 4;
/* Step over underscore */
pszUuid++;
uuid_obj->us_data3 = (u16) uuid_hex_to_bin(pszUuid, 4);
pszUuid += 4;
/* Step over underscore */
pszUuid++;
uuid_obj->uc_data4 = (u8) uuid_hex_to_bin(pszUuid, 2);
pszUuid += 2;
uuid_obj->uc_data5 = (u8) uuid_hex_to_bin(pszUuid, 2);
pszUuid += 2;
/* Step over underscore */
pszUuid++;
for (j = 0; j < 6; j++) {
uuid_obj->uc_data6[j] = (u8) uuid_hex_to_bin(pszUuid, 2);
pszUuid += 2;
}
}
