From: Matt Corallo Date: Thu, 30 Jun 2016 19:46:16 +0000 (+0000) Subject: net: stmmac: Fix null-function call in ISR on stmmac1000 X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a8b7d7709dc6db7d6d8a9a04aa9d49b029a27203;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git net: stmmac: Fix null-function call in ISR on stmmac1000 (resent due to overhelpful mail client corrupting patch) At least on Meson GXBB, the CORE_IRQ_MTL_RX_OVERFLOW interrupt is thrown with the stmmac1000 driver, which does not support set_rx_tail_ptr. With this patch and the clock fixes, 1G ethernet works on ODROID-C2. Signed-off-by: Matt Corallo Signed-off-by: David S.
