Subject: [PATCH 19/30] usb: host: isp1362: Mark the many unused ISP1362_REG entries as __maybe_unused
Date: Thu, 2 Jul 2020 15:46:14 +0100 [thread overview]
Message-ID: <20200702144625.2533530-20-lee.jones@linaro.org> (raw)
In-Reply-To: <20200702144625.2533530-1-lee.jones@linaro.org>
It would seem a shame to strip out all of the unused register entries,
since they can act as a fair source of documentation. Instead, mark
them all as __maybe_unused to show the build system that this behaviour
is known and intentional.
Fixes the following kernel build warning(s):
