Hello list,

inside the automatic U-Boot patch tracking system a new ticket [DNX#2006040142001347] was created:

<snip>

hi!

currently a series of 'pci_bus_to_hose() failed' messages are printed when pciinfo() is called with a invalid (out-of-bounds) bus number.

this patch fixes the output of the 'pci' command by *) checking that the given bus number is actually a number *) checking that the given bus number is not out-of-bounds before doing a scan *) printing 'pci_bus_to_hose() failed' only when DEBUG is defined

Signed-off-by: Horst Kronstorfer <hkronsto <at> frequentis.com>
