Please remove this empty line.

This is not indented correctly.

The ~() expression is part of the "cpum_val &", it's not
another separate argument to tw32().

Therefore ~() should be indented to the column cpum_val starts
at.

Why are you incrementing eeprom->len when you break out of the
loop due to a signal?  You didn't read that extra byte.
