Subject: [PATCH 1/4] lib/crc32.c: remove unneeded casts
Date: Thu, 13 Jan 2022 08:41:15 +0200	[thread overview]
Message-ID: <20220113064118.1580916-2-kevin@bracey.fi> (raw)
In-Reply-To: <20220113064118.1580916-1-kevin@bracey.fi>

Casts were added in 8f243af42ade ("sections: fix const sections for
crc32 table") to cope with the tables not being const. They are no
longer required since f5e38b9284e1 ("lib: crc32: constify crc32 lookup
table").
