From 5b87f355462a4d43904fd99873c0e3e0f439d4b6 Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Fri, 3 Nov 2023 10:47:16 +0200 Subject: mmc: cqhci: Increase recovery halt timeout [ Upstream commit b578d5d18e929aa7c007a98cce32657145dde219 ] Failing to halt complicates the recovery. Additionally, unless the card or controller are stuck, which is expected to be very rare, then the halt should succeed, so it is better to wait. Set a large timeout.
