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
