Hi, This series contains a single patch that fixes an issue in the rkisp1 filter mode configuration logic. The rkisp1_flt_config() function performs a direct write to the FILT_MODE register before the read/modify/write update. This write does not include the RKISP1_CIF_ISP_FLT_ENA bit, which clears the enable bit in hardware. After that, the read/modify/write sequence cannot restore the original enable state, causing the filter to be disabled unintentionally. The patch removes the redundant direct write. The remaining read/modify/write sequence correctly updates the mode fields while preserving the existing enable bit. Please review. Thanks, Rui Wang Rui Wang (1): media: rkisp1: Fix filter mode register configuration drivers/media/platform/rockchip/rkisp1/rkisp1-params.c | 6 ------ 1 file changed, 6 deletions(-) -- 2.43.0
