pcmcia: Change window_handle_t logic to unsigned long
Logic changes based on top of the other patches: This set of patches changed window_handle_t from being a pointer to an unsigned long. The unsigned long is now a simple index into socket->win[]. Going from a pointer to unsigned long should leave the user space interface unchanged unless I'm mistaken. This change results in code that is less error prone and a user space interface which is much cleaner and safer. A nice side effect is that we are also are able to remove all members except one from window_t. [ linux@dominikbrodowski.net: Update to 2.6.31. Also, a plain "index" to socket->win[] does not work, as several codepaths rely on "window_handle_t" being non-zero if used. Therefore, set the window_handle_t to the socket->win[] index + 1. ] CC: netdev@vger.kernel.org Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
