Subject: [PATCH] hw/timer/sse-timer: Propagate eventual error in sse_timer_realize()
Date: Fri, 12 Mar 2021 01:18:45 +0100	[thread overview]
Message-ID: <20210312001845.1562670-1-f4bug@amsat.org> (raw)

If the SSECounter link is absent, we set an error message
in sse_timer_realize() but forgot to propagate this error.
Add the missing 'return'.

Fixes: CID 1450755 (Null pointer dereferences)
Signed-off-by: Philippe Mathieu-Daudé <f4bug@amsat.org>
