parentx86/cpu: Fix overrun check in arch_print_cpu_modalias() (diff)
x86/cpu: Clean up modalias feature matching
We currently include commas on both sides of the feature ID in a modalias, but this prevents the lowest numbered feature of a CPU from being matched. Since all feature IDs have the same length, we do not need to worry about substring matches, so omit commas from the modalias entirely. Avoid generating multiple adjacent wildcards when there is no feature ID to match. Signed-off-by: Ben Hutchings <ben@decadent.org.uk> Acked-by: Thomas Renninger <trenn@suse.de> Acked-by: H.
