From 7bf47f609f7eaac4f7e9c407a85ad78997288a38 Mon Sep 17 00:00:00 2001 From: Sergei Shtylyov Date: Sat, 15 Feb 2020 23:10:53 +0300 Subject: [PATCH] sh_eth: check sh_eth_cpu_data::no_xdfar when dumping registers When adding the sh_eth_cpu_data::no_xdfar flag I forgot to add the flag check to __sh_eth_get_regs(), causing the non-existing RDFAR/TDFAR to be considered for dumping on the R-Car gen1/2 SoCs (the register offset check has the final say here)...
