Subject: x86, microcode, AMD: Remove unneeded memset call
X-Git-Tag: upstream/snapshot3+hdmi~11248^2~3
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=05ff02e4c0686051fcb074aec92df03f2c184fd1;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

x86, microcode, AMD: Remove unneeded memset call

collect_cpu_info_amd() clears its csig arg but this is done in the
microcode_core's collect_cpu_info() by clearing the embedding struct
ucode_cpu_info. Drop it.
