Subject: kexec_core: remove redundant 0 value initialization
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=13818f7b8c85c89aa97a430f8116490c1b833470;p=users%2Fhch%2Fmisc.git

kexec_core: remove redundant 0 value initialization

The kimage struct is already zeroed by kzalloc(). It's redundant to
initialize image->head to 0.
