+Fix building against 5.9 or newer kernels
+
+DECLARE_TASKLET was replaced with DECLARE_TASKLET_OLD in 5.9.
+Marking as inappropriate for upstream for now, as it seems the
+standalone version of the driver has been superceded by the version
+in the staging tree in the mainline kernel, and there are no obvious
+signs of maintenance.
+
+Upstream-Status: Inappropriate [no upstream]
+Signed-off-by: Scott Murray <scott.murray@konsulko.com>
