This avoids some resource leaks, is more in line with the error handling path of the probe function, and is more consistent with other drivers. Fixes: fb8bd90f83c4 ("mmc: sdhci-sprd: Add Spreadtrum's initial host controller") Signed-off-by: Christophe JAILLET Acked-by: Orson Zhai Acked-by: Adrian Hunter --- Other adjustment may be needed. I'm not sure at all of the 0 passed to 'sdhci_remove_host()'. Some drivers pass 0, some have some more complicated computation. --- drivers/mmc/host/sdhci-sprd.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/drivers/mmc/host/sdhci-sprd.c b/drivers/mmc/host/sdhci-sprd.c index f85171edabeb..5dc36efff47f 100644 --- a/drivers/mmc/host/sdhci-sprd.c +++ b/drivers/mmc/host/sdhci-sprd.c @@ -708,14 +708,14 @@ static int sdhci_sprd_remove(struct platform_device *pdev) { struct sdhci_host *host = platform_get_drvdata(pdev); struct sdhci_sprd_host *sprd_host = TO_SPRD_HOST(host); - struct mmc_host *mmc = host->mmc; - mmc_remove_host(mmc); + sdhci_remove_host(host, 0); + clk_disable_unprepare(sprd_host->clk_sdio); clk_disable_unprepare(sprd_host->clk_enable); clk_disable_unprepare(sprd_host->clk_2x_enable); - mmc_free_host(mmc); + sdhci_pltfm_free(pdev); return 0; }
