Subject: [PATCH] ARM: cacheinfo fix format field mask
Date: Wed, 15 Jan 2025 13:10:49 +0200 [thread overview]
Message-ID: <20250115-arm-cacheinfo-fix-v1-1-5f30eeb4e463@linaro.org> (raw)
Fix C&P error left unnoticed during the reviews. The FORMAT field spans
over bits 29-31, not 24-27 of the CTR register.
Fixes: a9ff94477836 ("ARM: 9433/2: implement cacheinfo support")
Reported-by: Marek Szyprowski <m.szyprowski@samsung.com>
Closes: https://lore.kernel.org/linux-arm-msm/01515ea0-c6f0-479f-9da5-764d9ee79ed6@samsung.com/
