skip check for "adapNr == busnr" to support symbolic links to bus numbers
## it's possible to create a symlink i2c-42 to the bus our i2c components are connected to

### MDIS Patch for i2c-42
// if ((cl-\>addr == shifted_addr) && (ent-\>adapNr == busnr)) if (cl-\>addr == shifted_addr)
this way the i2c drivers can be loaded in a different order and i2cdetect -y 42 is always correct
MDIS works with the bus 42 after this change. smb2_eeprod2 smb_42
