Subject: [PATCH net-next 1/8] net: ipa: don't use u32p_replace_bits()
Date: Thu, 22 Sep 2022 17:20:53 -0500	[thread overview]
Message-ID: <20220922222100.2543621-2-elder@linaro.org> (raw)
In-Reply-To: <20220922222100.2543621-1-elder@linaro.org>

In two spots we use u32_replace_bits() to replace a set of bits in a
register while preserving the rest.  Both of those cases just zero
the bits being replaced, and this can be done more simply without
using that function.
