Commit Message

Sakari Ailus May 27, 2025, 5:56 a.m. UTC 
Use 0x90 as the IOCTL number base instead of 0x80, thus avoiding using the
same IOCTL numbers as the Media Controller. The change is also in line
with current IOCTL number documentation.

Also use 0xaf, belonging to the samples IOCTL number range, as the
unimplemented IOCTL.
