Two small changes: make the IRQ name less generic, and stop
whining about certain non-errors (details in the patch comments).
Please merge.
- Dave
Make the 8250 UART driver register its IRQ using a label that's more
appropriate ... it's an 8250 UART, not one of dozens of other kind of
serial link (I2C, SPI, USB, McBSP, I2S, non-8250 UART, USART, SSP,
MicroWire, PS/2 kbd/mouse/touchpad, MCSI, HDQ/1-Wire, ... etc).
Also, make it stop whining when one of the platform serial ports has
been disabled, e.g. because a given board doesn't wire it out.
