Subject: [PATCH v2 08/12] media: atomisp: get rid of USE_WINDOWS_BINNING_FACTOR tests
Date: Wed, 17 Nov 2021 09:56:50 +0000	[thread overview]
Message-ID: <d7ab37bcddc7d7e13681dbb9841b455b0c0bdfe4.1637142905.git.mchehab+huawei@kernel.org> (raw)
In-Reply-To: <cover.1637142905.git.mchehab+huawei@kernel.org>

This is meant to select a platform-dependent factor between
Linux and Windows. It makes no sense to keep it on Kernel.
