-Subject: [PATCH] usb-devices: avoid dependency on bash
+Upstream-Status: Backport (https://github.com/gregkh/usbutils/commit/508d1acf42e1bfd470c6bf1a188574c69c20aeed)
+Signed-off-by: Ross Burton <ross.burton@intel.com>
 
-By virtue of having #!/bin/bash this script declared that it requires
-bash, however manual examination, checkbashisms and tests with dash
-and busybox show that it doesn't contain any bashisms, so change the
-header to avoid the dependency.
