In ti_hecc_xmit(), local variable "data" is not initialized before

This patch fixes the following sparse warning by adding the missing
__iomem annotation.
drivers/net/can/mscan/mscan.c:73:32: warning: incorrect type in argument 1 (different address spaces)

In this code, the failure_cleanup label calls the function
plx_pci_del_card, which frees everything in the card->net_dev array. dev
is placed in this array immediately after allocation, so the two subsequent
jumps to failure_cleanup should not also call free_sja1000dev, but the
second one does.
If plx_pci_check_sja1000 fails, then free_sja1000dev is also called on
dev. Because dev is already in the card->net_dev array, this implies that
when plx_pci_del_card is later called, it may get freed again. So that
entry is reset to NULL after the free.
Finally, if there is a problem with one channel, there will be a hole in the
array. card->channels counts the number of channels that have succeeded,
and does not keep track of the index of the largest element in the array
that is valid. So the loop in plx_pci_del_card is changed to go up to
PLX_PCI_MAX_CHAN, which is only 2.

This patch removes obsolete code in the initialisation/creation of
slcan devices.
It follows the suggested cleanups from Ilya Matvejchikov in
drivers/net/slip.c that where recently applied to net-next-2.6:
- slip: remove dead code within the slip initialization
- slip: remove redundant check slip_devs for NULL

Since we have a struct that defines the sizes of the registers, we don't
need to explicitly use the 16bit read/write helpers. Let the code figure
out which size access to make based on the size of the C type.
There should be no functional changes here.
