Subject: [PATCH v3][next] mtd: rawnand: stm32_fmc2: Fix fall-through warnings for Clang
Date: Fri, 5 Mar 2021 02:29:53 -0600	[thread overview]
Message-ID: <20210305082953.GA137771@embeddedor> (raw)

In preparation to enable -Wimplicit-fallthrough for Clang, fix a couple
of warnings by explicitly adding a couple of break statements instead
of letting the code fall through to the next case.

Link: https://github.com/KSPP/linux/issues/115
Signed-off-by: Gustavo A. R. Silva <gustavoars@kernel.org>
---
Changes in v3:
 Update the changelog text according to the actual code change.

Changes in v2:
 Make use of a break statement instead of fallthrough for consistency.
