Subject: [PATCH] mmc: tmio: remove workaround for NON_REMOVABLE
Date: Thu, 18 Feb 2021 12:02:24 +0100	[thread overview]
Message-ID: <20210218110224.6910-1-wsa+renesas@sang-engineering.com> (raw)

RPM handling has been improved twice since this comment, and also SCC
handling has been improved a lot. All the testing we did (Geert's and
Niklas' and Wolfram's board farms) with the workaround removed did not
lead to problems, so it is time to get rid of it to the best of our
knowledge.
