+Date: Fri, 9 Aug 2019 01:24:30 +0300
+Message-Id: <20190808222430.28477-1-digetx@gmail.com>
+X-Mailer: git-send-email 2.22.0

+
+The WRITE_PROTECT bit is always in a "protected mode" on Tegra and
+WP-GPIO state need to be used instead. In a case of the GPIO absence,
+write-enable should be assumed. External SD is writable once again as
+a result of this patch because the offending commit changed behaviour for
+the case of a missing WP-GPIO to fall back to WRITE_PROTECT bit-checking,
+which is incorrect for Tegra.
