[PATCH v3 0/2] Stop calling request_irq(), etc. with invalid IRQs in the USB drivers`

Here are 2 patches against the 'usb-linus' branch of GregKH's 'usb.git' repo.
The affected drivers call platform_get_irq() but largely ignore its result --
they blithely pass the negative error codes to request_irq() (and its ilk)
which expects *unsinged* IRQ #s. Stop doing that by checking what exactly
platform_get_irq() returns.

I've removed 7 patches that GregKH has applied to the usb-testing' branch
(holler if this isn't enough).

[1/2] usb: host: ohci-tmio: add IRQ check
[2/2] usb: phy: tahvo: add IRQ check
