'struct nand_ecc_engine_ops' are not modified in these drivers. Constifying this structure moves some data to a read-only section, so increases overall security, especially when the structure holds some function pointers. Update the prototype of mxic_ecc_get_pipelined_ops() accordingly. On a x86_64, with allmodconfig, as an example: Before: ====== text data bss dec hex filename 16709 1374 16 18099 46b3 drivers/mtd/nand/ecc-mxic.o After: ===== text data bss dec hex filename 16789 1294 16 18099 46b3 drivers/mtd/nand/ecc-mxic.o Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com> Link: https://lore.kernel.org/linux-mtd/72597e9de2320a4109be2112e696399592edacd4.1729271136.git.christophe.jaillet@wanadoo.fr
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 reStructuredText 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.
