mtd: onenand: Avoid fall-through warnings
NOTICE THAT: "...we don't know whether we need fallthroughs or breaks here and this is just a change to avoid having new warnings when switching to -Wimplicit-fallthrough but this change might be entirely wrong."[1] See the original thread of discussion here: https://lore.kernel.org/patchwork/patch/1036251/ So, in preparation to enabling -Wimplicit-fallthrough, this patch silences the following warnings: drivers/mtd/nand/onenand/onenand_base.c: In function ‘onenand_check_features’: drivers/mtd/nand/onenand/onenand_base.c:3264:6: warning: this statement may fall through [-Wimplicit-fallthrough=] if (ONENAND_IS_DDP(this)) ^ drivers/mtd/nand/onenand/onenand_base.c:3284:2: note: here case ONENAND_DEVICE_DENSITY_2Gb: ^~~~ drivers/mtd/nand/onenand/onenand_base.c:3288:17: warning: this statement may fall through [-Wimplicit-fallthrough=] this->options |= ONENAND_HAS_UNLOCK_ALL; drivers/mtd/nand/onenand/onenand_base.c:3290:2: note: here case ONENAND_DEVICE_DENSITY_1Gb: ^~~~ Warning level 3 was used: -Wimplicit-fallthrough=3 Also, notice that this patch doesn't change any functionality. See the most recent thread of discussion here: https://lore.kernel.org/patchwork/patch/1077395/ This patch is part of the ongoing efforts to enable -Wimplicit-fallthrough.

treewide: kzalloc() -> kcalloc()
The kzalloc() function has a 2-factor argument form, kcalloc(). This
patch replaces cases of:
kzalloc(a * b, gfp)
with:
kcalloc(a * b, gfp)
as well as handling cases of:
kzalloc(a * b * c, gfp)
with:
kzalloc(array3_size(a, b, c), gfp)
as it's slightly less ugly than:
kzalloc_array(array_size(a, b), c, gfp)
This does, however, attempt to ignore constant size factors like:
kzalloc(4 * 1024, gfp)
though any constants defined via macros get caught up in the conversion.
Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.
The Coccinelle script used for this was:

mtd: Move onenand code base to drivers/mtd/nand/onenand
Move onenand code base to the drivers/mtd/nand directory in the hope that someday someone will patch it to use the generic NAND helpers. If it never happens, at least we'll have all NAND related support in a single directory and not spread over the drivers/mtd/ directory. Signed-off-by: Boris Brezillon <boris.brezillon@bootlin.com> |
