x86, setup: Fix EDD3.0 data verification.
Check for nonzero path in edd_has_edd30() has no sense. First, it looks at the wrong memory. Device path starts at offset 30 of the info->params structure which is at offset 8 from the beginning of info structure, but code looks at info + 4 instead. This was correct when code was introduced, but around v2.6.4 three more fields were added to edd_info structure (commit 66b61a5c in history.git). Second, even if it will check correct memory it will always succeed since at offset 30 (params->key) there will be non-zero values otherwise previous check would fail. The patch replaces this bogus check with one that verifies checksum. Signed-off-by: Gleb Natapov <gleb@redhat.com> Link: http://lkml.kernel.org/r/20110426082132.GG2265@redhat.com Signed-off-by: H.
