    Subject[PATCH 5.15 155/917] quota: correct error number in free_dqentry()
    Date
    From: Zhang Yi <yi.zhang@huawei.com>

    commit d0e36a62bd4c60c09acc40e06ba4831a4d0bc75b upstream.

    Fix the error path in free_dqentry(), pass out the error number if the
    block to free is not correct.

    Fixes: 1ccd14b9c271 ("quota: Split off quota tree handling into a separate file")
