Subject: [PATCH AUTOSEL 4.19 29/66] sh_eth: check sh_eth_cpu_data::no_xdfar when dumping registers

From: Sergei Shtylyov <sergei.shtylyov@...entembedded.com>

[ Upstream commit 7bf47f609f7eaac4f7e9c407a85ad78997288a38 ]

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)...

Fixes: 4c1d45850d5 ("sh_eth: add sh_eth_cpu_data::cexcr flag")
