[LEDE-DEV] Fwd: [PATCH] ath9k: Add airtime fairness scheduler

[bart van zoest]

Hi Weedy and Toke,

I am trying to apply the patch using: "curl
https://patchwork.ozlabs.org/patch/699159/raw/ | git apply -v". Is the
following output normal?

<stdin>:60: trailing whitespace.
 <stdin>:65: trailing whitespace.
 <stdin>:67: space before tab in indent.
     bool has_queued;
<stdin>:69: trailing whitespace.
 <stdin>:74: space before tab in indent.
     struct ath_softc *sc;

Applied patch package/kernel/mac80211/patches/326-ath9k-Introduce-airtime-fairness-scheduling.patch
cleanly.
