WARNING: timeout (50) seems HZ dependent
Numeric constants passed to schedule_timeout() make the effective
timeout HZ dependent which does not seem intended.
Fixed up by converting the constant to jiffies with msecs_to_jiffies()
As this driver was introduced in the early 2.3 series it is most
likely assuming HZ=100 so the constant 50 is converted to 500ms.

Here's the set of driver core patches for 3.19-rc1.
They are dominated by the removal of the .owner field in platform
drivers. They touch a lot of files, but they are "simple" changes, just
removing a line in a structure.
Other than that, a few minor driver core and debugfs changes. There are
some ath9k patches coming in through this tree that have been acked by
the wireless maintainers as they relied on the debugfs changes.
Everything has been in linux-next for a while.

I'm not sure why, but the hlist for each entry iterators were conceived
list_for_each_entry(pos, head, member)
The hlist ones were greedy and wanted an extra parameter:
hlist_for_each_entry(tpos, pos, head, member)
Why did they need an extra pos parameter? I'm not quite sure. Not only
they don't really need it, it also prevents the iterator from looking
exactly like the list iterator, which is unfortunate.
Besides the semantic patch, there was some manual work required:
- Fix up the actual hlist iterators in linux/list.h
- Fix up the declaration of other iterators based on the hlist ones.
- A very small amount of places were using the 'node' parameter, this
was modified to use 'obj->member' instead.
- Coccinelle didn't handle the hlist_for_each_entry_safe iterator
properly, so those had to be fixed up manually.
The semantic patch which is mostly the work of Peter Senna Tschudin is here:

We have conflicting type qualifiers for "freg_t" in s390's ptrace.h and the
iphase atm device driver, which causes the compile error below.
Unfortunately the s390 typedef can't be renamed, since it's a user visible api,
nor can I change the include order in s390 code to avoid the conflict.
So simply rename the iphase typedef to a new name. Fixes this compile error:

We weren't clearing card->tx_skb[port] when processing the TX done interrupt.
If there wasn't another skb ready to transmit immediately, this led to a
double-free because we'd free it *again* next time we did have a packet to
send.
