wifi: utils: Get correct channel count (9e38bcc1) · Commits · Wenxi XU / zephyr

When channel range is configured in scan params, get the channel count from `chan_idx` instead of taking a difference of start and end of the channel range. The `difference` method fails in case of 5GHz band since channels may not be consecutive numbers. Signed-off-by:
