The recent commit to delay the release of kobject triggered NULL dereferences of opti9xx drivers. The cause is that all snd-opti92x-ad1848, snd-opti92x-cs4231 and snd-opti93x drivers register the PnP card driver with the very same name, and also snd-opti92x-ad1848 and -cs4231 drivers register the ISA driver with the same name, too. When these drivers are built in, quick "register-release-and-re-register" actions occur, and this results in Oops because of the same name is assigned to the kobject. The fix is simply to assign individual names. As a bonus, by using KBUILD_MODNAME, the patch reduces more lines than it adds. The fix is based on the suggestion by Russell King.
