    Add patch fixing compilation warning related to if clause not guarding in
    wl_iw.c
    Fix compilation warning:
    /__w/openwrt/openwrt/openwrt/build_dir/target-mipsel-openwrt-linux-musl_musl/linux-bcm47xx_legacy/broadcom-wl-5.10.56.27.3/driver/wl_iw.c: In function 'wl_iw_set_freq':

      393 |         if (fwrq->m > 4000 && fwrq->m < 5000)
          |         ^~

      396 |                 chan = wf_mhz2channel(fwrq->m, sf);
          |                 ^~~~
    cc1: all warnings being treated as errors
