[PATCH 17/32] rt2x00: Put net_device structure in data_ring
From: Ivo van Doorn <[EMAIL PROTECTED]>
Change the structure stored in the data_ring structure
from the rt2x00_pci or rt2x00_usb to net_device.
This allows for better type checking, and the net_dev
is more often used in the interrupt handlers.

No need for a cast here.
In C you can cast from any struct pointer to void pointer and back
without problems.

No need for casting.
Many more of them.
I guess you could just do a fgrep for "*ring = (struct data_ring*)data;"

Thanks,
Not only the data_ring has unneeded casts, but they are also found on some
other locations.
I'll create a patch that removes them all.
