[PATCH 43/49] pcmcia: cleanup device driver header file
Dominik Brodowski
linux at dominikbrodowski.net
Mon Oct 13 13:48:28 EDT 2008
The header file primarily used for (in-kernel) PCMCIA device drivers
also deserved a major cleanup. This header file also serves as the dumping
ground for all typedefs and definitions only used by the deprecated PCMCIA
ioctl and the deprecated PCMCIA userspace tools using this ioctl.
