commit 31b35400cf77e788fec3d1c9fe590cdbb3544fd4 Author: Warner Losh <[email protected]> AuthorDate: 2021-12-14 22:16:42 +0000 Commit: Warner Losh <[email protected]> CommitDate: 2021-12-14 22:27:47 +0000 pccard: Remove more of the PC Card infrastructure Remove more of the pccard infrasturcture. CardBus Yenta driver (cbb) still references the remaining bits. It needs some additiona work to remove 16-bit support still, so it remains.
