Carlos was getting WARNING: at drivers/pci/pci.c:118 pci_ioremap_bar+0x24/0x52() when probing his sound card, and sound did not work. After adding pci=use_crs to the kernel command line, no more trouble. Ok, we can add a quirk. dmidecode output reveals that this is an MSI MS-7253, for which we already have a quirk, but the short-sighted author tied the quirk to a single BIOS version, making it not kick in on Carlos's machine with BIOS V1.2. If a later BIOS update makes it no longer necessary to look at the _CRS info it will still be harmless, so let's stop trying to guess which versions have and don't have accurate _CRS tables.

Reported-by: Carlos Luna <caralu74@xxxxxxxxx> Signed-off-by: Jonathan Nieder <jrnieder@xxxxxxxxx> --- Hi, Could you squash this into the patch "x86/PCI: use host bridge _CRS info on MSI MS-7253", if it's not too late? Sorry for the thinko.
