Subject: staging: ks7010: refactor ks_wlan_set_sleep_mode function
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=7f3c8bb5bcf3a133d1eeb171cf90888bc5253a69;p=openwrt%2Fstaging%2Fblogic.git

staging: ks7010: refactor ks_wlan_set_sleep_mode function

This commit refactors ks_wlan_set_sleep_mode function
avoiding to use switch-case statement ans using simple
if logic to handle invalid values first. This simplifies
data paths as well as improves readability.
