From: Jia-Ju Bai <redacted>

The memory allocated by kzalloc in b43_bus_dev_ssb_init and
b43_bus_dev_bcma_init is not freed.
This patch fixes the bug by adding kfree in b43_ssb_remove,
b43_bcma_remove and error handling code of b43_bcma_probe.

Thanks Michael for his suggestion.

This stalled waiting for testing on BCMA.

The fix _looks_ correct.

For BCMA, b43_bus_dev_bcma_init() allocs the memory that wldev->dev ends
up pointing to, however it appears that this memory is never freed. Hunks
1 and 2 add that freeing to the probe and remove functions respectively.

Hunk 1 makes b43_bcma_probe()'s error handling look like b43_ssb_probe()'s.

Thanks,

Julian Calaby
