Last change on this file since 82261 was 81590, checked in by vboxsync, 5 years ago

pdmdev.h: Adding type-safer PDMDEVINS_2_DATA and PDMDEVINS_2_DATA_CC macros that replaces PDMINS_2_DATA and PDMINS_2_DATA_CC for device instances. On modern compilers these macros will check the size type against the size in the device registration structure, though only in strict builds of course. bugref:9218
