Subject: [PATCH] bitfield: Restore be16_replace_bits()
Date: Wed, 23 Sep 2026 23:09:53 +0100	[thread overview]
Message-ID: <20260923-bitfield-be16_replace_bits-v1-1-71b6388b8385@kernel.org> (raw)

Commit 1c88ceb09d5e5 ("bitfield: get rid of __MAKE_OP machinery")
removed a bunch of unused bitfield operations including
be16_replace_bits() but commit 508bdb4938928 ("iio: adc: Add AD7768 and
AD7768-4 core support") introduces a new user.  Restore the function so
the build still works once both branches are merged.
