Subject: [PATCH][hotplug] Proper hexnum support for USB sysfs tree
Date: Wed, 17 Mar 2004 22:46:29 +0000 [thread overview]
Message-ID: <20040317224629.GC2267@pasky.ji.cz> (raw)
Hello,
the hotplug's default usb.agent doesn't handle properly hex numbers in the
USB sysfs tree, the trivial patch below should fix that. Otherwise each USB
hotplug run produces few very annoying kind-of '[: 0a: integer expression
expected' errors.
