Subject: [PATCH 07/32] kmsan: Remove a useless assignment from kmsan_vmap_pages_range_noflush()
Date:   Wed, 15 Nov 2023 21:30:39 +0100
Message-ID: <20231115203401.2495875-8-iii@linux.ibm.com>

The value assigned to prot is immediately overwritten on the next line
with PAGE_KERNEL. The right hand side of the assignment has no
side-effects.

Fixes: b073d7f8aee4 ("mm: kmsan: maintain KMSAN metadata for page operations")
