From 8762442fe9997b663746b25b89c092aa228f8f15 Mon Sep 17 00:00:00 2001 From: Seunghwan Baek Date: Thu, 29 Aug 2024 15:18:22 +0900 Subject: [PATCH] mmc: cqhci: Fix checking of CQHCI_HALT state commit aea62c744a9ae2a8247c54ec42138405216414da upstream. To check if mmc cqe is in halt state, need to check set/clear of CQHCI_HALT bit. At this time, we need to check with &, not &&.
