Hi all
On an ARM system with a 2.6.18 kernel the zd1211rw driver based on the current
git head fails probe() with the following debug output:
zd1211rw usb_init()

Whereas earlier versions (latest tested
83c15ac14de7a01633c07e1c68226c73f9c92421) work fine. A short look through the
diffs reveal critical differences like read16 vs. read32, and changed __packed__
attributes. Any idea what the likely reason can be?
Thanks
