Subject: [REGRESSION]: bcma: fix handling of big addrl

The above commit causes a regression for me.

Booting with initcall_debug shows that bcma_modinit never returns:

calling bcma_modinit+0x0/0x33 [bcma] @ 210
bcma-pci-bridge 0000:02:00.0: enabling device (0000 -> 0002)
bcma: bus0: Found chip with id 0xA8D8, rev 0x01 and package 0x08

Which means that (obviously) my wireless nic doesnot work (doe not
show up in "ip addr"). Moreover, the kernel hangs during reboot and
I'm forced to do a hard-reboot.

Reverting the offending commit on top of 3.12-rc1 fixes the problem.

Cheers,

Tom

Hi,

There is already a patch in wireless-testing on its way into linux tree:

Thanks for the reference, hadn't seen that. FWIW, it works for me.

Cheers,
