This write\ndoes not include the RKISP1_CIF_ISP_FLT_ENA bit, which clears the\nenable bit in hardware. After that, the read/modify/write sequence\ncannot restore the original enable state, causing the filter to be\ndisabled unintentionally.\n\nThe patch removes the redundant direct write. The remaining\nread/modify/write sequence correctly updates the mode fields while\npreserving the existing enable bit.\n\nPlease review.\n\nThanks,\nRui Wang\n\nRui Wang (1):\n media: rkisp1: Fix filter mode register configuration\n\n drivers/media/platform/rockchip/rkisp1/rkisp1-params.c | 6 ------\n 1 file changed, 6 deletions(-)" }
