The patch is wordwrapped, has spaces replaced by tabs and each version is
subtly different from its predecessor. This confuses me.
Please confirm that the below is the appropriate and final patch, thanks.
From: "Om Narasimhan" <[email protected]>
The previous code did something like,
if (error) goto out_err;
....
do {
struct au1000_pcmcia_socket *skt = PCMCIA_SOCKET(i);
del_timer_sync(&skt->poll_timer);
pcmcia_unregister_socket(&skt->socket);
out_err:
flush_scheduled_work();
ops->hw_shutdown(skt);
i--;
} while (i > 0)
.....
- On the error path, skt would not contain a valid value for the first
iteration (skt is masked by uninitialized automatic skt)
- Does not do hw_shutdown() for 0th element of PCMCIA_SOCKET
