Subject: [PATCH] crypto: omap - Drop obsolete PageSlab check
Date: Thu, 24 Jun 2021 14:35:29 +0800 [thread overview]
Message-ID: <20210624063529.GA2057@gondor.apana.org.au> (raw)
As it is now legal to call flush_dcache_page on slab pages we
no longer need to do the check in the omap driver. This patch
also uses flush_dcache_page instead of flush_kernel_dcache_page
because the page we're writing to could be anything.
