scsi: aic94xx: fix module loading

James Bottomley · martinkpetersen · commit 42caa0edabd6 · 2019-02-01T18:04:07.000-05:00
The aic94xx driver is currently failing to load with errors like sysfs: cannot create duplicate filename '/devices/pci0000:00/0000:00:03.0/0000:02:00.3/0000:07:02.0/revision' Because the PCI code had recently added a file named 'revision' to every PCI device. Fix this by renaming the aic94xx revision file to aic_revision. This is safe to do for us because as far as I can tell, there's nothing in userspace relying on the current aic94xx revision file so it can be renamed without breaking anything. Fixes: 702ed3b (PCI: Create revision file in sysfs) Cc: stable@vger.kernel.org Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com> Signed-off-by: Martin K.
