[PATCH AUTOSEL 6.1 01/25] ASoC: Intel: bytcr_rt5640: Apply Asus T100TA quirk to Asus T100TAM too

by Sasha Levin

From: Hans de Goede <hdegoede(a)redhat.com> [ Upstream commit e50729d742ec364895f1c389c32315984a987aa5 ] The Asus T100TA quirk has been using an exact match on a product-name of "T100TA" but there are also T100TAM variants with a slightly higher clocked CPU and a metal backside which need the same quirk. Sort the existing T100TA (stereo speakers) below the more specific T100TAF (mono speaker) quirk and switch from exact matching to substring matching so that the T100TA quirk will also match on the T100TAM models.

While softlockup warnings can be harmless, they can also interfere with things like RCU freeing memory, which can be problematic when the kdump kexec image is configured with as little memory as possible. Avoid the softlockup, and give things like work items and RCU a chance to do their thing during __read_vmcore by adding a cond_resched.
