Subject: watchdog: wm8350_wdt: Fix handling WDIOS_DISABLECARD/WDIOS_ENABLECARD options
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ebe06e826faed9d710c3d49fe336c74b5f3a5f2a;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

watchdog: wm8350_wdt: Fix handling WDIOS_DISABLECARD/WDIOS_ENABLECARD options

While receiving WDIOS_DISABLECARD option for WDIOC_SETOPTIONS command,
call wm8350_wdt_stop() to disable watchdog.
Call wm8350_wdt_start() while receiving WDIOS_ENABLECARD option.

Current code has reverse behavior.
