mtd: maps: pcmciamtd: fix potential memory leak in pcmciamtd_detach()

2025-11-17T10:49:14+00:00

The memory allocated for struct pcmciamtd_dev in pcmciamtd_probe() is not freed in the corresponding remove function pcmciamtd_detach(). Fix that by freeing it in the remove function. Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2") Signed-off-by: Abdun Nihaal Signed-off-by: Miquel Raynal

mtd: Switch back to struct platform_driver::remove()

2024-10-21T09:58:07+00:00

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/mtd to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer.

mtd: physmap: Use -y instead of -objs in Makefile

2024-05-27T11:39:53+00:00

*-objs suffix is reserved rather for (user-space) host programs while usually *-y suffix is used for kernel drivers (although *-objs works for that purpose for now). Let's correct the old usages of *-objs in Makefiles.

mtd: maps: sa1100-flash: Prefer struct_size over open coded arithmetic

2024-04-09T06:35:37+00:00

This is an effort to get rid of all multiplications from allocation functions in order to prevent integer overflows [1][2]. As the "info" variable is a pointer to "struct sa_info" and this structure ends in a flexible array: struct sa_info { [...] struct sa_subdev_info subdev[]; }; the preferred way in the kernel is to use the struct_size() helper to do the arithmetic instead of the calculation "size + size * count" in the kzalloc() function. This way, the code is more readable and safer. This code was detected with the help of Coccinelle, and audited and modified manually.

mtd: maps: physmap-core: fix flash size larger than 32-bit

2024-02-26T10:26:21+00:00

mtd-ram can potentially be larger than 4GB. get_bitmask_order() uses fls() that is not guaranteed to work with values larger than 32-bit. Specifically on aarch64 fls() returns 0 when all 32 LSB bits are clear. Use fls64() instead.
