A common pattern with skb_put() is to just want to memcpy()
some data into the new space, introduce skb_put_data() for
this.
An spatch similar to the one for skb_put_zero() converts many
of the places using it:

The timer handling in this driver is broken in several ways:
- corkscrew_open() initializes and arms a timer before requesting the
device interrupt. If the request fails the timer stays armed.
A second call to corkscrew_open will unconditionally reinitialize the
quued timer and arm it again. Also a immediate device removal will leave
the timer queued because close() is not called (open() failed) and
therefore nothing issues del_timer().
The reinitialization corrupts the link chain in the timer wheel hash
bucket and causes a NULL pointer dereference when the timer wheel tries
to operate on that hash bucket. Immediate device removal lets the link
chain poke into freed and possibly reused memory.
Solution: Arm the timer after the successful irq request.
- corkscrew_close() uses del_timer()
On close the timer is disarmed with del_timer() which lets the following
code race against a concurrent timer expiry function.
Solution: Use del_timer_sync() instead
- corkscrew_close() calls del_timer() unconditionally
del_timer() is invoked even if the timer was never initialized. This
works by chance because the struct containing the timer is zeroed at
allocation time.
Solution: Move the setup of the timer into corkscrew_setup().

With centralized MTU checking, there's nothing productive done by
eth_change_mtu that isn't already done in dev_set_mtu, so mark it as
deprecated and remove all usage of it in the kernel. All callers have been
audited for calls to alloc_etherdev* or ether_setup directly, which means
they all have a valid dev->min_mtu and dev->max_mtu. Now eth_change_mtu
prints out a netdev_warn about being deprecated, for the benefit of
out-of-tree drivers that might be utilizing it.
Of note, dvb_net.c actually had dev->mtu = 4096, while using
eth_change_mtu, meaning that if you ever tried changing it's mtu, you
couldn't set it above 1500 anymore. It's now getting dev->max_mtu also set
to 4096 to remedy that.
