Subject: amd64_edac: fix ecc_enable_override handling
X-Git-Tag: v2.6.31-rc2~80^2~1
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=30c875cbc1836a03a1acc6c998fa8a04f29f8f73;p=profile%2Fivi%2Fkernel-x86-ivi.git

amd64_edac: fix ecc_enable_override handling

amd64_check_ecc_enabled() returns non-zero status when ECC
checking/correcting is disabled and this fails further loading of the
driver even when 'ecc_enable_override' boot param is used.

Fix that by clearing return status in that case.
