Subject: watchdog: wafer5823wdt: Fix handling WDIOS_DISABLECARD/WDIOS_ENABLECARD options
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8a062ac693d5597b3c5d0e347ce7d1d82b967698;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

watchdog: wafer5823wdt: Fix handling WDIOS_DISABLECARD/WDIOS_ENABLECARD options

While receiving WDIOS_DISABLECARD option for WDIOC_SETOPTIONS command,
call wafwdt_stop() to disable watchdog.
Call wafwdt_start() while receiving WDIOS_ENABLECARD option.

Current code has reverse behavior.
