* Reformat to match kernel tabbing style.
* Add CDROM_GET_UPC ioctl.
* 3.10 Apr 10, 1996 -- Fix compilation error with STANDARD_ATAPI.
- * 3.11 Apr 29, 1996 -- Patch from Heiko Eissfeldt <heiko@colossus.escape.de>
+ * 3.11 Apr 29, 1996 -- Patch from Heiko Eißfeldt <heiko@colossus.escape.de>
* to remove redundant verify_area calls.
* 3.12 May 7, 1996 -- Rudimentary changer support. Based on patches
* from Gerhard Zuber <zuber@berlin.snafu.de>.
* - Minimize the TOC reading - only do it when we
* know a media change has occurred.
* - Moved all the CDROMREADx ioctls to the Uniform layer.
- * - Heiko Eissfeldt <heiko@colossus.escape.de> supplied
+ * - Heiko Eißfeldt <heiko@colossus.escape.de> supplied
* some fixes for CDI.
* - CD-ROM leaving door locked fix from Andries
