    Subject[PATCH 5.7 272/477] mfd: wcd934x: Drop kfree for memory allocated with devm_kzalloc
    Date
    From: Wei Yongjun <weiyongjun1@huawei.com>

    [ Upstream commit 652b7b6740eb52d98377a881c7730e36997f00ab ]

    It's not necessary to free memory allocated with devm_kzalloc
    and using kfree leads to a double free.

    Fixes: 6ac7e4d7ad70 ("mfd: wcd934x: Add support to wcd9340/wcd9341 codec")
