+Subject: [PATCH 034/165] usb: musb: omap: fix the error check for
+ pm_runtime_get_sync
+
+commit ad579699c4f0274bf522a9252ff9b20c72197e48 upstream.
+
+pm_runtime_get_sync returns a signed integer. In case of errors
+it returns a negative value. This patch fixes the error check
+by making it signed instead of unsigned thus preventing register
+access if get_sync_fails. Also passes the error cause to the
+debug message.
