BugLink: https://bugs.launchpad.net/bugs/2019320 User space expects /dev/i2c-* device entries but in raspi 6.2 the i2c-dev driver is compiled as a module which is not auto-loaded, hence no device entries. The driver is small enough to not have a significant impact on kernel memory consumption for applications that don't need i2c, so compile it into the kernel (as in previous releases).
