+Subject: [PATCH] vm-support: fix build for kernel's > 5.14
+
+* remove set_driver_byte call
+* not sure if it's still necessary here, but set_driver_byte as well as DRIVER_SENSE was killed in 5.14 with:
+  https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=464a00c9e0ad45e3f42ff6ea705491a356df818e
+
+  in some cases it was replaced with set_status_byte(sc, SAM_STAT_CHECK_CONDITION), but I didn't
+  read the implementation carefully enough to decide if this is still needed, I was only interested
+  in fixing the build failure (and I don't use this at all to test it in runtime)
+
+Upstream-Status: Inappropriate [embedded specific]
