Subject: ath5k: don't enable MSI, we cannot handle it yet
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=256b152b005e319f985f50f2a910a75ba0def74f;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

ath5k: don't enable MSI, we cannot handle it yet

MSI is a nice thing, but we cannot enable it without changing the
interrupt handler.  If we do it, we break MSI capable hardware,
specifically AR5006 chipset.
