From b80148710983d05edb2d9a6066e19f480a2971ab Mon Sep 17 00:00:00 2001 From: Miaohe Lin Date: Mon, 5 Sep 2022 18:27:54 +0800 Subject: [PATCH] block: remove unneeded return value of bio_check_ro() [ Upstream commit bdb7d420c6f6d2618d4c907cd7742c3195c425e2 ] bio_check_ro() always return false now. Remove this unneeded return value and cleanup the sole caller. No functional change intended.
