So i said an exact match, which this is not.
How about something like:
static u8 vsc85xx_edge_rate_magic_get(u16 vddmac, u8 slowdown)
{
u8 vdd;
u8 sd;
for (vdd = 0; vdd < ARRAY_SIZE(edge_table); vdd++)
if (edge_table[vdd].vddmac == vddmac)
for (sd = 0; sd < MSCC_SLOWDOWN_MAX; sd++)
if (edge_table[vdd].slowdown[sd] == slowdown)
return (MSCC_SLOWDOWN_MAX - sd - 1);
return -EINVAL;
}
