Subject: [PATCH 093/283] net: hns3: Fix a memory leak in an error handling
path in 'hclge_handle_error_info_log()'
mainline inclusion
from mainline-v5.14-rc1
commit b40d7af798a0a459d65bd95f34e3dff004eb554a
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/I8EMUR
CVE: NA
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=b40d7af798a0a459d65bd95f34e3dff004eb554a
----------------------------------------------------------------------
If this 'kzalloc()' fails we must free some resources as in all the other
error handling paths of this function.
Fixes: 2e2deee7618b ("net: hns3: add the RAS compatibility adaptation solution")
