Your patch forgot to include these:

Why would a net driver have files in include/asm/?
Have some comments-via-diff, mainly trivial:
From: Andrew Morton <[email protected]>
- Nuke the typedef
- Reduce exorbitant inlining.
- possible bug: tsi108_open() does request_irq() as its first operation.
The IRQ handler can run immediately. Is it ready for that?
- Use setup_irq().
- Unneeded casts of void*
- alloc_etherdev() already zeroes the memory.
- why are tsi108_prv_data.regs and .phyregs volatile? They shouldn't be.
- What's this?
data->regs = (u32)ioremap(einfo->regs, 0x400); /*FIX ME */
data->phyregs = (u32)ioremap(einfo->phyregs, 0x400); /*FIX ME */
- Use DEFINE_SPINLOCK()
- Use free_netdev(), not kfree() (Is this right?)
- Use mod_timer()
- tsi108_init_phy() has a 10-millisecond busywait in it, seemingly
needlessly. Convert to msleep().
- tsi108_init_phy() has multiple potentially infinite wait loops. Add
timeouts.
- Random coding-style cleanups.
