Convert pm_runtime_enable() to the managed version, and clean up error handling and unnecessary .remove() callback accordingly. Signed-off-by: Fei Shao <fshao@xxxxxxxxxxxx> --- Changes in v2: Use devm_pm_runtime_enable() per suggestion from the previous thread: https://lore.kernel.org/lkml/20230510164330.z2ygkl7vws6fci75@xxxxxxxxxxxxxx/T/#m25be91afe3e9554600e859a8a59128ca234fc63d .../mediatek/vcodec/mtk_vcodec_dec_hw.c | 26 ++++++------------- 1 file changed, 8 insertions(+), 18 deletions(-) diff --git a/drivers/media/platform/mediatek/vcodec/mtk_vcodec_dec_hw.c b/drivers/media/platform/mediatek/vcodec/mtk_vcodec_dec_hw.c index b753bf54ebd9..e1cb2f8dca33 100644 --- a/drivers/media/platform/mediatek/vcodec/mtk_vcodec_dec_hw.c +++ b/drivers/media/platform/mediatek/vcodec/mtk_vcodec_dec_hw.c @@ -148,20 +148,21 @@ static int mtk_vdec_hw_probe(struct platform_device *pdev) ret = mtk_vcodec_init_dec_clk(pdev, &subdev_dev->pm); if (ret) return ret; - pm_runtime_enable(&pdev->dev); + + ret = devm_pm_runtime_enable(&pdev->dev); + if (ret) + return ret; of_id = of_match_device(mtk_vdec_hw_match, dev); if (!of_id) { dev_err(dev, "Can't get vdec subdev id.\n"); - ret = -EINVAL; - goto err; + return -EINVAL; } hw_idx = (enum mtk_vdec_hw_id)(uintptr_t)of_id->data; if (hw_idx >= MTK_VDEC_HW_MAX) { dev_err(dev, "Hardware index %d not correct.\n", hw_idx); - ret = -EINVAL; - goto err; + return -EINVAL; } main_dev->subdev_dev[hw_idx] = subdev_dev; @@ -173,36 +174,25 @@ static int mtk_vdec_hw_probe(struct platform_device *pdev) if (IS_SUPPORT_VDEC_HW_IRQ(hw_idx)) { ret = mtk_vdec_hw_init_irq(subdev_dev); if (ret) - goto err; + return ret; } subdev_dev->reg_base[VDEC_HW_MISC] = devm_platform_ioremap_resource(pdev, 0); if (IS_ERR((__force void *)subdev_dev->reg_base[VDEC_HW_MISC])) { ret = PTR_ERR((__force void *)subdev_dev->reg_base[VDEC_HW_MISC]); - goto err; + return ret; } if (!main_dev->subdev_prob_done) main_dev->subdev_prob_done = mtk_vdec_hw_prob_done; platform_set_drvdata(pdev, subdev_dev); - return 0; -err: - pm_runtime_disable(subdev_dev->pm.dev); - return ret; -} - -static int mtk_vdec_hw_remove(struct platform_device *pdev) -{ - pm_runtime_disable(&pdev->dev); - return 0; } static struct platform_driver mtk_vdec_driver = { .probe = mtk_vdec_hw_probe, - .remove = mtk_vdec_hw_remove, .driver = { .name = "mtk-vdec-comp", .of_match_table = mtk_vdec_hw_match, -- 2.40.1.606.ga4b1b128d6-goog
