Subject: [PATCH] ARM: ep93xx: Add terminator to gpiod_lookup_table
Date: Mon, 5 Feb 2024 11:23:34 +0100 [thread overview]
Message-ID: <20240205102337.439002-1-alexander.sverdlin@gmail.com> (raw)
From: Nikita Shubin <nikita.shubin@maquefel.me>
Without the terminator, if a con_id is passed to gpio_find() that
does not exist in the lookup table the function will not stop looping
correctly, and eventually cause an oops.
Cc: stable@vger.kernel.org
Fixes: b2e63555592f ("i2c: gpio: Convert to use descriptors")
