Subject[PATCH 5.18 84/88] EDAC/synopsys: Use the correct register to disable the error interrupt on v3 hw
Date
From: Sherry Sun <sherry.sun@nxp.com>

commit be76ceaf03bc04e74be5e28f608316b73c2b04ad upstream.

v3.x Synopsys EDAC DDR doesn't have the QOS Interrupt register. Use the
ECC Clear Register to disable the error interrupts instead.

Fixes: f7824ded4149 ("EDAC/synopsys: Add support for version 3 of the Synopsys EDAC DDR")
