Subject: [PATCH AUTOSEL 5.4 206/266] input: i8042 - Remove special PowerPC handling
Date: Wed, 17 Jun 2020 21:15:31 -0400 [thread overview]
Message-ID: <20200618011631.604574-206-sashal@kernel.org> (raw)
In-Reply-To: <20200618011631.604574-1-sashal@kernel.org>
From: Nathan Chancellor <natechancellor@gmail.com>
[ Upstream commit e4f4ffa8a98c24a4ab482669b1e2b4cfce3f52f4 ]
This causes a build error with CONFIG_WALNUT because kb_cs and kb_data
were removed in commit 917f0af9e5a9 ("powerpc: Remove arch/ppc and
include/asm-ppc").

Presumably since nobody has noticed this for the last 12 years, there is
not anyone actually trying to use this driver so we can just remove this
special walnut code and use the generic header so it builds for all
configurations.
