meta-phosphor: Move layer content from common/
Adopt a more conventional directory hierarchy. meta-phosphor is still
a _long_ way from suitable for hosting on yoctoproject.org but things
like this don't help.

In this case, there's the +possibility of restarting this program from the state of +the watchdog device not being properly stopped (done by writing +a 'V' and closing the device). Since it wasn't stopped, the +driver may not be able to restart the watchdog when this program +reopens it and starts pinging it. + +To fix this, the code will always first issue the stop when it +starts up. + +Signed-off-by: Matt Spinler <spinler@us.ibm.com> +--- + miscutils/watchdog.c | 21 +++++++++++++++++++-- + 1 file changed, 19 insertions(+), 2 deletions(-) + +diff --git a/miscutils/watchdog.c b/miscutils/watchdog.c +index 07ae64e52..223e3c32d 100644 +--- a/miscutils/watchdog.c ++++ b/miscutils/watchdog.c +@@ -53,6 +53,24 @@ static void watchdog_shutdown(int sig UNUSED_PARAM) + _exit(EXIT_SUCCESS); + } + ++static void watchdog_open(const char* device) ++{ ++ static const char magic_value = 'V'; ++ ++ /* If the watchdog driver can do something other than cause a reboot ++ * on a timeout, then it's possible this program may be starting from ++ * a state when the watchdog hadn't been previously stopped with ++ * the magic write followed by a close.
