2018-12-01kbuild: announce removal of SUBDIRS if usedMasahiro Yamada
SUBDIRS has been kept as a backward compatibility since commit ("[PATCH] kbuild: external module support") in 2002. We do not need multiple ways to do the same thing, so I will remove SUBDIRS after the Linux 5.3 release. I cleaned up in-tree code, and updated the document so that nobody would try to use it. Meanwhile, display the following warning if SUBDIRS is used. Makefile:189: ================= WARNING ================ Makefile:190: 'SUBDIRS' will be removed after Linux 5.3 Makefile:191: Please use 'M=' or 'KBUILD_EXTMOD' instead Makefile:192: ========================================== Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Acked-by: Boris Brezillon <boris.brezillon@bootlin.com> # for scx200_docflash.c Acked-by: Guenter Roeck <linux@roeck-us.net> # for scx200_wdt.c

2018-11-20mtd: spi-nor: fix selection of uniform erase type in flexible confTudor.Ambarus@microchip.com
There are uniform, non-uniform and flexible erase flash configurations. The non-uniform erase types, are the erase types that can _not_ erase the entire flash by their own. As the code was, in case flashes had flexible erase capabilities (support both uniform and non-uniform erase types in the same flash configuration) and supported multiple uniform erase type sizes, the code did not sort the uniform erase types, and could select a wrong erase type size. Sort the uniform erase mask in case of flexible erase flash configurations, in order to select the best uniform erase type size. Uniform, non-uniform, and flexible configurations with just a valid uniform erase type, are not affected by this change. Uniform erase tested on mx25l3273fm2i-08g and sst26vf064B-104i/sn. Non uniform erase tested on sst26vf064B-104i/sn.

2018-11-18mtd: rawnand: atmel: fix OF child-node lookupJohan Hovold
Use the new of_get_compatible_child() helper to lookup the nfc child node instead of using of_find_compatible_node(), which searches the entire tree from a given start node and thus can return an unrelated (i.e. non-child) node. This also addresses a potential use-after-free (e.g. after probe deferral) as the tree-wide helper drops a reference to its first argument (i.e. the node of the device being probed). While at it, also fix a related nfc-node reference leak.

2018-11-05mtd: rawnand: fsmc: Fix unchecked return value in fsmc_read_page_hweccGustavo A. R. Silva
Check return value of nand_read_data_op. Notice that, currently, all instances of nand_read_data_op() are being checked, with the exception of two of them in marvell_nand driver, in which the caller function explicitly returns 0 every time. Also, notice that I moved the declaration of *ret* to the top of fsmc_read_page_hwecc(). Addresses-Coverity-ID: 1471968 ("Unchecked return value") Signed-off-by: Gustavo A. R.
