Hi Prabhakar, I'm skipping this patch since if I am not mistaken this patch fixes this as well (as part of a larger overhaul): https://patchwork.linuxtv.org/project/linux-media/patch/20220113041055.25213-9-yunfei.dong@mediatek.com/ I posted a PR for that series, so that's on the way in. Please confirm so I can mark your patch as Superseded.

Hi All, This patch series aims to drop using platform_get_resource() for IRQ types in preparation for removal of static setup of IRQ resource from DT core code. Dropping usage of platform_get_resource() was agreed based on the discussion [0]. [0] https://patchwork.kernel.org/project/linux-renesas-soc/ patch/20211209001056.29774-1-prabhakar.mahadev-lad.rj@bp.renesas.com/ Cheers, Prabhakar Lad Prabhakar (13): media: vsp1: Use platform_get_irq() to get the interrupt media: camss: Use platform_get_irq_byname() to get the interrupt media: bdisp: Use platform_get_irq() to get the interrupt media: s5p-mfc: Use platform_get_irq() to get the interrupt media: stm32-dma2d: Use platform_get_irq() to get the interrupt media: davinci: vpif: Use platform_get_irq_optional() to get the interrupt media: exynos-gsc: Use platform_get_irq() to get the interrupt media: marvell-ccic: Use platform_get_irq() to get the interrupt media: mtk-vcodec: Drop unnecessary call to platform_get_resource() media: exynos4-is: Use platform_get_irq() to get the interrupt media: s5p-g2d: Use platform_get_irq() to get the interrupt media: mtk-vpu: Drop unnecessary call to platform_get_resource() media: coda: Use platform_get_irq() to get the interrupt drivers/media/platform/coda/imx-vdoa.c | 9 ++++--- drivers/media/platform/davinci/vpif.c | 18 ++++++++------ drivers/media/platform/davinci/vpif_capture.c | 24 ++++++++++++------- drivers/media/platform/davinci/vpif_display.c | 21 ++++++++++------ drivers/media/platform/exynos-gsc/gsc-core.c | 14 +++++------ drivers/media/platform/exynos4-is/fimc-core.c | 11 ++++----- drivers/media/platform/exynos4-is/fimc-lite.c | 11 ++++----- .../media/platform/marvell-ccic/mmp-driver.c | 8 +++---- .../platform/mtk-vcodec/mtk_vcodec_dec_drv.c | 11 ++++----- .../platform/mtk-vcodec/mtk_vcodec_enc_drv.c | 10 +++----- drivers/media/platform/mtk-vpu/mtk_vpu.c | 10 +++----- .../media/platform/qcom/camss/camss-csid.c | 12 ++++------ .../media/platform/qcom/camss/camss-csiphy.c | 12 ++++------ .../media/platform/qcom/camss/camss-ispif.c | 12 ++++------ drivers/media/platform/qcom/camss/camss-vfe.c | 12 ++++------ drivers/media/platform/s5p-g2d/g2d.c | 10 +++----- drivers/media/platform/s5p-mfc/s5p_mfc.c | 11 ++++----- drivers/media/platform/sti/bdisp/bdisp-v4l2.c | 10 +++----- drivers/media/platform/stm32/dma2d/dma2d.c | 9 +++---- drivers/media/platform/vsp1/vsp1_drv.c | 14 +++++------ 20 files changed, 108 insertions(+), 141 deletions(-)
