From: Sergei Shtylyov Date: Sat, 6 Feb 2016 14:47:22 +0000 (+0300) Subject: ravb: skip gPTP start/stop on R-Car gen3 X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=50bfd83830b89f9273672dcaedf3b765724fd023;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git ravb: skip gPTP start/stop on R-Car gen3 When adding support for the R-Car gen3 gPTP active in configuration mode, some call sites of ravb_ptp_{init|stop}() were missed due to an oversight. Add checks for the R-Car gen2 SoCs around these... Fixes: f5d7837f96e5 ("ravb: ptp: Add CONFIG mode support") Signed-off-by: Sergei Shtylyov Signed-off-by: David S.
