Subject: [PATCH 0/2] watchdog: fixes for menz069_wdt driver
Date: Tue, 18 Apr 2023 19:25:29 +0200 [thread overview]
Message-ID: <20230418172531.177349-1-jth@kernel.org> (raw)
While testing the Qemu emulation of the menz069_wdt watchdog core, I've found
two issues in the kernel driver.
On is a NULL pointer dereference, because the driver can't access it's
private data and one is a wrong register read resulting in incorrect timeout
values being set.

watchdog: menz069_wdt: fix watchdog initialisation
watchdog: menz069_wdt: fix timeout setting
