In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. This patch fixes the following warnings: drivers/mtd/chips/cfi_util.c: In function ‘cfi_build_cmd’: drivers/mtd/chips/cfi_util.c:110:10: warning: this statement may fall through [-Wimplicit-fallthrough=] onecmd |= (onecmd << (chip_mode * 32)); ~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/mtd/chips/cfi_util.c:112:2: note: here case 4: ^~~~ drivers/mtd/chips/cfi_util.c:113:10: warning: this statement may fall through [-Wimplicit-fallthrough=] onecmd |= (onecmd << (chip_mode * 16)); ~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/mtd/chips/cfi_util.c:114:2: note: here case 2: ^~~~ drivers/mtd/chips/cfi_util.c: In function ‘cfi_merge_status’: drivers/mtd/chips/cfi_util.c:163:7: warning: this statement may fall through [-Wimplicit-fallthrough=] res |= (onestat >> (chip_mode * 32)); ~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/mtd/chips/cfi_util.c:165:2: note: here case 4: ^~~~ drivers/mtd/chips/cfi_util.c:166:7: warning: this statement may fall through [-Wimplicit-fallthrough=] res |= (onestat >> (chip_mode * 16)); ~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/mtd/chips/cfi_util.c:167:2: note: here case 2: ^~~~ Warning level 3 was used: -Wimplicit-fallthrough=3 This patch is part of the ongoing efforts to enabling -Wimplicit-fallthrough.

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
