Subject: [PATCH 4.19 105/120] sh_eth: fix TRSCER mask for R7S72100

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

[ Upstream commit 75be7fb7f978202c4c3a1a713af4485afb2ff5f6 ]

According  to  the RZ/A1H Group, RZ/A1M Group User's Manual: Hardware,
Rev. 4.00, 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 R7S72100.
