From 2b31251a64777c01ede787691954d7d6fbda64c6 Mon Sep 17 00:00:00 2001 From: Warner Losh Date: Wed, 6 Dec 2017 23:05:15 +0000 Subject: [PATCH] Now that cam_periph_runccb() can be called from situations where the kernel scheduler is stopped, replace the by hand calling of xpt_polled_action() with it.
