[PATCH 0/2] Random PARISC patches

[-- Attachment #1: Type: text/plain, Size: 425 bytes --]

This little series has 2 patches that have nothing to do with each other 
beyond the point that I stumbled over both of these things today.

The first one fixes a compile error if CONFIG_PCI is not set, e.g. for the 
Apollo 705 I have. This is also needed in 3.2, although it covers also 
pci_iomap() in this case which was moved to lib/ by a recent patch.

The other one is just a minor code cleanup in the HIL driver.

[PATCH 2/2] HIL: remove one goto

Subject: [PATCH 2/2] HIL: remove one goto

This goto is only used to skip the next instruction, which can easily be done
without a goto.

It looks to me like this could be further simplified with an &&.
