Hi Rafał,

Just some minor feedback on coding style. I wanted to make a change in 
host_pci.c to avoid changing the PCI BAR window and noticed following:
1. indentation is all spaces.
2. initial indent is 7 spaces, and subsequent indents are 8 spaces.
3. pointer assignment: ptr =&var;
4. output parameter: foo(bar,&yabar);

I am not sure whether checkpatch.pl triggers on any of these, but can we 
fix at least items 1) and 2).
