From 0bdf9b3dd3cfa5cbd5d55172c19f5dd166208e17 Mon Sep 17 00:00:00 2001 From: Magnus Damm Date: Wed, 13 Dec 2006 19:46:53 +0900 Subject: 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 Signed-off-by: Dominik Brodowski --- drivers/pcmcia/pcmcia_ioctl.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'drivers/pcmcia/pcmcia_ioctl.c') diff --git a/drivers/pcmcia/pcmcia_ioctl.c b/drivers/pcmcia/pcmcia_ioctl.c index c829ead5cdb7..6245fde02b79 100644 --- a/drivers/pcmcia/pcmcia_ioctl.c +++ b/drivers/pcmcia/pcmcia_ioctl.c @@ -916,12 +916,12 @@ static int ds_ioctl(struct inode * inode, struct file * file, goto free_out; break; case DS_GET_FIRST_WINDOW: - ret = pcmcia_get_window(s, &buf->win_info.handle, 0, + ret = pcmcia_get_window(s, &buf->win_info.handle, 1, &buf->win_info.window); break; case DS_GET_NEXT_WINDOW: ret = pcmcia_get_window(s, &buf->win_info.handle, - buf->win_info.handle->index + 1, &buf->win_info.window); + buf->win_info.handle + 1, &buf->win_info.window); break; case DS_GET_MEM_PAGE: ret = pcmcia_get_mem_page(s, buf->win_info.handle, -- cgit v1.2.3
