Subject: LU-4629 lmv: fix issue found by Klocwork Insight tool
X-Git-Tag: 2.5.57~53
X-Git-Url: https://git.whamcloud.com/?p=fs%2Flustre-release.git;a=commitdiff_plain;h=809f0371c5046f0c4f532c5e0fa8985e42f9a547

LU-4629 lmv: fix issue found by Klocwork Insight tool

'plock.cookie' might be used uninitialized in this function.

sscanf format specification '%d' expects type 'int *' for 'd',
but parameter 3 has a different type '__u32*'
