Subject: watchdog: ep93xx_wdt.c: fix platform probe
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=697b41e4d4b20b8d8564f5501927b0ed07153990;p=openwrt%2Fstaging%2Fblogic.git

watchdog: ep93xx_wdt.c: fix platform probe

Fix the device/driver init so that the misc_register
happens as last (since this opens userspace access to
the device).
