Subject: [PATCH v2] console: console: Complete exception handling in newport_probe()
Date: Thu, 23 Apr 2020 14:26:27 +0000 [thread overview]
Message-ID: <20200423142627.1820-1-zhengdejin5@gmail.com> (raw)
A call of the function ¡°do_take_over_console¡± can fail here.
The corresponding system resources were not released then.
Thus add a call of the function ¡°iounmap¡± together with the check
of a failure predicate.
Fixes: e84de0c6190503 ("MIPS: GIO bus support for SGI IP22/28")
