    Subject[PATCH 5.15 367/913] mmc: davinci_mmc: Handle error for clk_enable
    Date
    From: Jiasheng Jiang <jiasheng@iscas.ac.cn>

    [ Upstream commit 09e7af76db02c74f2a339b3cb2d95460fa2ddbe4 ]

    As the potential failure of the clk_enable(),
    it should be better to check it and return error
    if fails.

    Fixes: bbce5802afc5 ("davinci: mmc: updates to suspend/resume implementation")
