Would it be > problematic to just allow "^atmel,(24(c|cs|mac)[a-z0-9]+|spd)$"? I) "^atmel,(24(c|cs|mac)[a-z0-9]+|spd)$" : The first pattern does not specify where the digits must occur within the alphanumeric sequence that follows 24c, 24cs, or 24mac. It allows the sequence to be all letters, all digits, or any mix thereof. II) "^atmel,(24(c|cs|mac)[0-9]+[a-z0-9]*|spd)$" : The second pattern specifically requires that at least one digit appears immediately after 24c, 24cs, or 24mac, and only after this digit can letters appear. As hypothetical example : atmel,24cabc would match the first pattern but not the second because there are no digits immediately following 24c. atmel,24c123 would match both patterns because there are digits immediately following 24c, and the first pattern doesn't care about the position of the digits within the alphanumeric sequence. In case of at24,mac02e4 and at24,mac02e6 match both patterns. Let me know your thoughts. I agree to change the pattern as you suggest. BR, Andrei
