Subject: [PATCH 5.11 115/306] sh_eth: fix TRSCER mask for R7S9210

From: Greg Kroah-Hartman <gregkh@...uxfoundation.org>

From: Sergey Shtylyov <s.shtylyov@...russia.ru>

commit 165bc5a4f30eee4735845aa7dbd6b738643f2603 upstream.

According  to the RZ/A2M Group User's Manual: Hardware, Rev. 2.00,
the TRSCER register has bit 9 reserved, hence we can't use the driver's
default TRSCER mask.  Add the explicit initializer for sh_eth_cpu_data::
trscer_err_mask for R7S9210.
