Subject: [PATCH v4 11/19] auxdisplay: ht16k33: Remove unneeded error check in keypad probe()
Date: Tue, 27 Jul 2021 16:04:51 +0200 [thread overview]
Message-ID: <20210727140459.3767788-12-geert@linux-m68k.org> (raw)
In-Reply-To: <20210727140459.3767788-1-geert@linux-m68k.org>
There is no need to check the return code of input_register_device(),
just propagate it to the caller.
