From a83150eaad42769e4d08b6e07956a489e40214ae Mon Sep 17 00:00:00 2001 From: Stanislaw Gruszka Date: Tue, 16 Oct 2018 09:58:43 +0200 Subject: [PATCH] mt76x0: do not perform MCU calibration for MT7630 Driver works better for MT7630 without MCU calibration, which looks like it can hangs the firmware. Vendor driver do not perform it for MT7630 as well.
