Subject: [PATCH] r8169: improve checking for valid LED modes
|
|
|
|
After 3a2746320403 ("leds: trigger: netdev: Display only supported link
|
|
speed attribute") the check for valid link modes can be simplified.
|
|
In addition factor it out, so that it can be re-used by the upcoming
|
|
LED support for RTL8125.
