category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAGELE

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=0298f51652be47b79780833e0b63194e1231fa34



--------------------------------

It was reported that recent fix for memory corruption during topology
load, causes corruption in other cases. Instead of being overeager with
checking topology, assume that it is properly formatted and just
duplicate strings.
