Subject: ARM: 9440/1: cacheinfo fix format field mask
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=f520fab580c9179bacc432f3a3bf1eada73fdfcc;p=users%2Fdwmw2%2Flinux.git

ARM: 9440/1: cacheinfo fix format field mask

Fix C&P error left unnoticed during the reviews. The FORMAT field spans
over bits 29-31, not 24-27 of the CTR register.

Closes: https://lore.kernel.org/linux-arm-msm/01515ea0-c6f0-479f-9da5-764d9ee79ed6@samsung.com/
